about 3 minutes.

tomato sauce method:

main ingredient: tomato, 25g

auxiliary material: high-alcohol liquor, 25ml

1. Wash the tomato for later use.

2. Wash the bottles in advance, control the water to dry, and rinse them one by one with high-alcohol liquor (the wine can be poured into one bottle and then poured into another)

3. Peel the tomatoes, break them into small pieces and put them into bottles, not too full. If it is a small mouth bottle, it should be broken into small pieces and poured into the bottle through the funnel.

4. Tighten the cover.

5. put cold water into the pot, and the water is half the height of the bottle. Boil for 3 minutes.

6. Let it stand for 3 minutes after cooking, then take it out and tighten the lid again. (Because the heat expands and contracts, the lid will be loose when it is cooked, so check it, or the lid will be broken if it leaks. )

7. This is the cooked tomato sauce. Put it in a ventilated place, cool it thoroughly and put it in a box and keep it in the basement. It's no problem to keep it for one to two years, but we usually destroy it in one year. The key to making tomato sauce is to keep the bottle clean, do not touch the oil, and the lid should be tight so as not to leak.
