If I want to multiply recipes and make for 20 people, then should I multiply all the ingredients?

Yes, you can multiply the recipes by increasing the quantity of each ingredient. Refer to the conversion table while scaling up the recipes.However, please keep in mind the following points:

1. Cooking time will increase due to larger quantities. 2. High-flavour ingredients like salt, lemon, black pepper powder, green chili, spices, etc., should be used in lesser quantities when multiplying the recipe by 10 to 20 times.
