Because you usually use a small oven at home, you can't practice the same amount as a practical exam. This app calculates different ingredients at the same rate based on the amount of one material. Ex) When making chocolate muffins, if you break the egg and weigh 50g, calculate the weight of the other ingredients at a time of 83.33g, 50g sugar, 50g butter, and 0.83g salt. If you are not sure how to make each item, you can refer to the recipe hints or write down a brief note. In the new version, you can add/modify/delete personal recipes. You can enter the recipe found on the book or the Internet and calculate it at a desired rate.
