For this project, we will make strawberry jam. Keep in mind, though, that other similarly pulpy and juicy fruits can also be made into jam.
[related|post]You will need a total about P2,508 to buy the ingredients for this project in bulk. If you just want to try out making jam, though, you need not buy the whole lot. For instance, you can simply buy 200 g of citric acid for P50 instead of paying P110 for a whole kilo.
Most of the utensils and equipment you will need for this project should already be available in your kitchen: measuring spoons and cups, gas stove, casserole, pressure cooker, ladle, containers, mixing bowl, and packaging bottle with lag-type cap (a box of 24 pieces of this costs P150).
STEP 1: Measure the ingredients and put them in individual containers. Then mix all the dry ingredients—the sugar, the food gel, and the citrus pectin. You may also mix the citric acid together with the other dry ingredients. Usually, though, the citric acid is best added after cooking the jam. This is because jams, depending on the quality of sugar and fruit used, tend to become either too sweet or too sour after cooking. So to get the desired taste—whether you want it on the sour or sweet side—add just the right amount of citric acid.
You must also carefully choose the quality of the sugar you are going to use. Keep in mind that commercially available granulated sugar is milder in taste than the finer sugars. Recommended for this particular jam recipe is the refined sugar that’s available in public markets.
STEP 2: After putting all the dry ingredients onto the bowl, mix them thoroughly until all the ingredients could no longer be individually identified. You need to make sure of this because if the ingredients are not mixed well, the citrus pectin won’t dissolve in the mixture. (Citrus pectin also does not dissolve directly in water.) Afterwards, set aside the mixture. Get the strawberries, wash them thoroughly, and remove their sepals (these are the leaf-like parts on top of the fruit). Press the fruits in a bowl using a spoon until you obtain 1/4 cup of the crushed fruit, including its juice. Make sure that you have thoroughly crushed the strawberries. Set aside.
Pour the water into the casserole, followed by the crushed strawberries, the juice and the mixed dry ingredients. Stir and blend all the ingredients until they are thoroughly mixed.
STEP 3: When the ingredients, except for the pieces of the crushed strawberry, have already dissolved, allow the mixture to simmer on high fire. Continuously stir to prevent scorching and forming bubbles. When the mixture starts to boil, lower the fire and allow the mixture to simmer until it achieves a thick enough consistency.
