How to make thick blackberry jam. Baking with blackberries

Blackberries are a tasty, healthy and aromatic berry. A close relative of raspberries, it has a distinct taste with sweet notes and slight sourness. It’s not surprising that blackberry jam always turns out appetizing and is loved by kids and adults alike. The thick delicacy can be spread on bread, added to pancakes, used as a filling for pies, etc. In addition, it helps strengthen the walls of blood vessels, cope with colds, and reduce body temperature.

Cooking features

To get jam without a single seed, you need to keep the fruits in hot water for several minutes, then rub through a fine sieve or cheesecloth. Upon release, all excess seeds will remain on the sieve, and the mass can be used further. If you need to leave whole berries for jam, then you should not wash them before cooking. And during cooking, carefully stir with a wooden spatula so as not to damage the pulp.

It is advisable to cook the jam in a wide and voluminous bowl or pan. It is best not to disturb it, but only occasionally shake the container. To get a fragrant and brighter dessert, you can use the juice or zest of lemon and orange.

Correct selection and preparation of berries

To choose ripe fruits for jam, use the following tips:

  1. 1. When choosing berries, pay attention only to ripe and elastic ones. If the blackberries are overripe or soft, the resulting delicacy will be too liquid. And unripe fruits will lead to the formation of sourness in the jam.
  2. 2. Before harvesting the berries, you need to sort them out and remove any adhering debris, leaves and dust. Wash and peel the fruits - a prerequisite.
  3. 3. It is important to pour the jam only into sterilized jars, which will retain all the beneficial substances of the sweetness and will not allow it to quickly deteriorate even when opened. To process them, just use an oven or boil the containers in boiling water along with the lids for several minutes. But you can close the jars with lids made of different materials, which depends on the method of preparing and storing the dessert.

Blackberry jam without seeds

The recipe will require the following products:

  • 1 kilogram of blackberries;
  • 1 kilogram of granulated sugar;

Classic recipe

To prepare the classic version of blackberry jam, you only need berries and sugar in equal quantities.

The berries are carefully and thoroughly washed, sorted and dried in a colander. Afterwards, the blackberries are transferred to a cooking container and covered with sugar. The berry-sugar mixture should be left for half an hour for the juice to appear. Next, the container is put on fire and slowly boiled until thick. Thirty minutes will be enough to get the desired consistency.

Place jam in pre-washed and sterilized jars up to the neck and seal tightly with lids. The containers are turned upside down, wrapped in a warm blanket, and after cooling, they are stored in a cool place until consumed.

"Five Minute"

Products for cooking:

  • one kilogram of fresh berries;
  • one kilogram of granulated sugar;
  • three grams of citric acid.

A five-minute recipe is a very quick way to make delicious jam. First of all, you need to sort the berries, wash them and let the liquid drain. Place blackberries in a large bowl or saucepan, alternating layers with sugar, and leave for five hours to soak.

After the specified time, place the pan on the fire, bring to a boil and cook for 5 minutes. Add citric acid and cook for another 5 minutes. Place the jam in jars, cover with plastic lids and store in the refrigerator.

  • one lemon;
  • kilogram of sugar;
  • kilogram of berries.

The fruits are sorted and washed to remove any remaining bushes. The orange is also washed, the zest is cut off and grated very finely. The juice is squeezed out of the orange, which will be the base of the jam. It goes into the container where the delicacy will be cooked. Sugar and zest are added to it. The mixture is brought to a boil over low heat.

The result should be a syrup that needs to be cooled, add berries and leave for a couple of hours. After two hours, the pan is put back on low heat for half an hour. Ten minutes before readiness, add lemon juice. The jam turns out very tasty and aromatic.

Jam with apples

  • a kilogram of fresh blackberries;
  • kilogram of apples;
  • one and a half kilograms of sugar;
  • lemon;
  • a tablespoon of odorless vegetable oil;
  • one hundred grams of liquor;
  • three hundred milliliters of water.

The apples need to be washed, cut into quarters, cored and cut into thin slices. Place them in a saucepan, add water and blanch for about ten minutes to soften the fruits. The juice is squeezed out of the lemon and sent to the apples. Next, blackberries are added to them. Cook for ten minutes, stirring constantly and skimming off the foam. Add liqueur and spices as desired and cook for a couple more minutes.

You can remove the pan from the stove, add oil to the mixture, mix everything well and skim off the foam. The jam should cool down. The finished dessert is poured into jars, covered with parchment paper on top and closed with plastic lids.

Banana flavored jam

Ingredients:

  • kilogram of blackberries;
  • kilogram of bananas;
  • kilogram of sugar.

We wash and clean the berries. You can place them on a paper towel to drain excess liquid and dry the fruits. Place the prepared blackberries in a container with a thick bottom, cover with sugar and leave overnight to release the juice. At this time, cut the bananas into slices or cubes.

Pour the jam into prepared jars, roll up or cover with polyethylene lids. The delicacy must be stored in a refrigerator or cellar at a low temperature.

Frozen fruit jam

Frozen blackberries are just as excellent and healthy to prepare as fresh ones. Whole frozen fruits are quite suitable for the recipe. You will need the following ingredients:

  • 500 grams of frozen blackberries and strawberries;
  • 1 kilogram of sugar;
  • 2 tablespoons lemon juice.

Frozen berries are placed in a saucepan, sprinkled with sugar and left to steep for a couple of hours. Blackberries and strawberries will release juice, which then needs to be scooped out of the container. Add a little lemon juice for a pleasant sourness. Next, put the pan on low heat, wait until the berry mixture boils, and cook for five minutes.

The pan should have high sides, because the jam will rise high during boiling. After this, the mass can be left to cool slightly and poured into clean sterilized jars, closed with lids and put away until cold weather sets in.

Plums and blackberries

Various fruits and berries are often added to blackberries, which make the jam much more tasty and aromatic. To prepare a delicacy with plums and cloves you will need:

After the specified time, use a masher to turn the contents into a puree, place on a sieve and leave to drain overnight. Place all the juice in a saucepan, add sugar and cook until sugar syrup is obtained. Next, increase the heat and cook for another twenty minutes with the fruit. The jam can be poured into prepared jars, closed with lids, and stored until winter.

Cooking problem

The cooking time for blackberry jam directly depends on the chosen recipe and the ingredients it contains. To make jam or preserves thick, you can cook for one to two hours. But sometimes ten minutes is enough, especially if the recipe uses whole berries that should not be boiled. You can also make jam in a slow cooker using a special mode.

The beneficial properties of blackberry jam are known to everyone. But with prolonged heat treatment, the berries lose all the microelements that the body needs during the cold season. To avoid this, many people grind blackberries with sugar in equal proportions.

  • lemon - 2 pcs.;
  • granulated sugar - 1 kg;

In order for blackberries to please you all year round, you need to make a supply for the winter. Simply put, freeze the required amount of product. This is a recipe for freezing blackberries without sugar.

What you will need:

  • blackberry;
  • bags for freezing food.

What to do:

  1. Remove all debris, leaves, and dirt from the berries. Remove crushed and spoiled berries too.
  2. Carefully wash the berries. Drain the water and dry the blackberries.
  3. Line a metal tray with parchment. Place all the berries on it in one layer. Be sure to line the tray with parchment. Otherwise, the berries will stick to it and will fall apart when you try to get them out.
  4. If there are more berries than can fit on the tray, you can cheat and, having frozen one layer, lay more parchment on top and place the berries on it in a second layer.
  5. Place the tray with berries in the freezer so that the berries do not roll down the tray and freeze them completely.
  6. After the berries freeze and become “glassy,” you need to transfer them to plastic bags for freezing food.
  7. Remove all air from the bags, seal them carefully and carefully place them in the freezer.
  8. If it is not important for you whether the berries freeze together or not, then the steps associated with the tray should be omitted. In this case, the berries can be placed in bags immediately after they are completely dry.

This freezing method guarantees that the product will be stored for at least six months.


The principle of operation is similar to that indicated in the recipe for freezing without sugar. The differences are as follows:

  • Naturally - adding sugar. The proportion is always the same, 1 to 1;
  • carefully mix the processed and dried berries in a large bowl with sugar, being careful not to damage the blackberries;
  • let the sugar-berry mixture stand;
  • package the resulting mixture in freezer bags or plastic containers;
  • place the workpiece in the freezer.

It is very convenient to use containers for freezing ice with this method - pack blackberry puree with sugar into small cells, freeze, and then pour the resulting cubes into a plastic bag.

In winter, raw jam without cooking reminds you of the taste of summer, besides, it retains quite a lot of vitamins, so it is not only tasty, but also healthy. This preparation of berries for the winter is made without heat treatment during preparation. Grinded blackberries with sugar will not ferment; they taste more juicy and aromatic than regular jam. A huge advantage will be the fact that you don’t have to pore over a bowl of boiling jam, constantly stirring it. Preparing pureed blackberries without cooking is easier and faster.

The only drawback of pureed berries is the storage method. Unfortunately, you can’t seal a lot of this jam, since the workpiece must be stored in the refrigerator; in addition, it can be put in the freezer (in this case, use much less sugar). Hence, the method of packing the jam should also be taken into account. Since glass containers are not intended to be frozen, blackberries are instead placed in ziplock bags, plastic bottles, or disposable containers with a tight lid. But this is a reliable way to preserve the taste of berries and their beneficial properties.

Blackberries without cooking, pureed with sugar for the winter

blackberry recipe for the winter without cooking

For those who are going to roll up pureed blackberries and then store them in the refrigerator, it is better to choose glass jars with iron lids. The jars are sterilized, dried, after which the jam is laid out in them, and they are rolled up with a boiled lid.

Ingredients:

  • 500g blackberries;
  • 750g sugar.

Cooking process:

You need more sugar than berries, since it is responsible for preservation and the ability to store the seaming for a long time.

First of all, you need to prepare the berries: remove all leaves, twigs and small debris. Then rinse under running water.


Wet berries are dried on a sieve for about half an hour, after which they need to be ground into puree. A blender is best suited for these purposes; it will grind the sweet berries to the consistency of porridge in just 3 minutes. If you don’t have a blender, you can use a meat grinder with a fine chopping attachment. You can also try to do this manually using a makogon, mortar or similar device.


There are quite a lot of small seeds in blackberries; if you want a more homogeneous jam, you need to strain the resulting puree through a sieve. The cake with seeds is useful for compote, so you should not throw them away.

Sugar is gradually added to the berry puree. Small portions of sugar are immediately stirred until it is completely dissolved. Due to the large presence of granulated sugar, the puree will become thinner, but when cooled, the puree will be thick enough to use as a sauce for sweet pancakes and other desserts.


Blackberries pureed with sugar are placed in jars like this. A layer of sugar is poured on top, and only after that it can be closed with a screw lid and sent to the refrigerator. This raw blackberry jam is best served cold. Frozen blackberry jam must first be thawed.
