Use vinegar or lemon, etc.

For people who don't eat onion, ginger and garlic, the problem of deodorizing food may be a little difficult. But there are actually some ways you can try.

First of all, you can use lemon or vinegar for deodorization. This is because both lemon and vinegar contain a lot of acids that can neutralize the amino acids in foods such as meat, thus achieving the deodorizing effect. When cooking, you can add lemon juice or vinegar to the ingredients and stir well, or drizzle lemon juice or vinegar over them after cooking.

Secondly, you can use some spices for deodorization. For example, spices such as peppercorns, cloves and star anise have deodorizing properties. When cooking, you can add these spices to the ingredients to stir, or put them on the bottom of the pot to boil, and then put the ingredients to cook.

Finally, you can also use some other seasonings to deodorize, such as ginger juice, cooking wine, white pepper and so on. All of these seasonings can help remove the fishy flavor from the ingredients and improve the taste of the food.

All in all, although not eating onion, ginger and garlic will cause some difficulties in deodorization, but there are still many other methods that can be tried. You need to choose and try them on a case-by-case basis to find the method that works best for you.
