Materials: fresh blueberries (as many as you want), lemon (1), sugar (a little)

Steps:

1. Wash the blueberries and put them into a stainless steel pot; wash, wash, wash, wash, wash, wash, wash, wash, wash, wash, wash, wash. The ratio of sugar to blueberries in the online tutorials is 8:1, but I'm going by feel, 750 grams of blueberries actually add up to 20 grams of sugar, and it's still very sweet;

3. Lemon cut in half, and then in front of your daughter-in-law with a smile on your face, you've actually been squeezing as hard as you can! To show your mighty side, squeeze the lemon flat! By the way, lemon juice squeezed into the pot;

4. boil on high heat and reduce to low heat, stirring constantly, there is only one principle: do not paste;

5. half an hour of cooking, do not idle during the period: rummage through the cupboard to find unused bottles, wash and put in a big pot of hard cooking bottles, not to eat the bottles but to sterilize it;

6. wait for the form of the blueberries from the blue-purple orb basically turned into a sauce on the supermarket shelves (the sauce is a kind of sauce, but not a sauce). Supermarket shelves of the sauce (about half an hour), turn off the heat to cool;

7. quickly called his daughter-in-law to taste, and then the two people with extremely exaggerated expression to each other to brag about the sweetness of the blueberry sauce, and then to the 5-month-old doll coated with a face, and then the two people together around the dolls of the dumbfounded do not know what happened to the dolls hahahaha

8. in the bottling before, don't eat all of them, leave a little.
