The methods of making frosting generally refer to removing oil to make frosting and weathering to make frosting. As for making frosting by lifting or by-products, we will not give examples here.

1 Croton cream: Grind clean croton kernels into a paste, press to remove oil, until loose and powdery, sift to obtain.

Or take clean croton kernels and grind them finely, measure the fat and oil content, add an appropriate amount of starch and mix well to make the oil content 18% to 20%, and sift to get it.

Peel the croton seeds: soak the single grains of croton seeds in thick rice soup and mix them, then expose them to the hot sun. After the seed coats burst, rub them off with a wooden board. Take the pure kernels and grind them into a paste. Wrap them with several layers of oil-absorbing paper to flatten them.

Cake shape, pressurize until the paper absorbs oil until it is transparent, take it out and grind it again, replace it with paper and pressurize it to remove the oil. Repeat this several times until the oil is basically removed. When it is loose, sieve it, grind the coarse particles again, and press to remove the oil.

Get everything through the sieve.

Notes: It is advisable to keep the temperature at 35 to 40°C during operation; wear masks, rubber gloves and other protective equipment to avoid contact with skin; tools used should be cleaned in time, and the replaced paper should be burned.

2 Watermelon Frost: Wash and dry the watermelon, cut off one end of the melon stem (reserve it as a cover), scoop out part of the inner flesh, fill it with 10% peel salt, cover the mouth, and hang it in a cool and ventilated place with a net bag to let it naturally

Precipitate the salt frost, scrape it and grind it finely. Or chop the watermelon and mix it with 10% saltpeter. Put it into a clean mud jar, seal it and put it in a cool and ventilated place. When the salt frost precipitates outside the jar, scrape it and grind it finely.

, that’s it.

Notes: Avoid sunlight, flies, and dust. After salt and frost are precipitated, scrape them off in time to avoid affecting the continued precipitation.
