STEP 1/7
It is a round cherry tomato and two kinds of jujube cherry tomatoes that look long like jujube. I washed the tomatoes clean, removed the top, and trimmed them. It is 1.1 kg of trimmed cherry tomatoes.
STEP 3/7
Put the ground tomatoes in a blender into a pot, pour 770g of sugar, and mix them evenly. I put in about two-thirds of the amount of sugar in the tomatoes.
STEP 4/7
Bring to a boil over a gas fire while stirring. When it is about to boil over, add 4 tablespoons of vinegar and bring to a boil while stirring evenly. Vinegar also has a sterilizing effect, but jam also solidifies quickly. So, if you boil it with vinegar in advance, the time to make jam is shortened, so it's convenient.
