Stoichiometry is the scientific method of measuring the quantitative proportions of one element to another. When conducting chemical reactions, it is important to carry out stoichiometric calculations to achieve an accurate and successful reaction. Furthermore, stoichiometry is used to decide which reactant is limiting and the amount of products formed.
Stoichiometry can be and has been applied when preparing food and its application is most commonly known in recipes. To cook your food the exact way you want would require you to prepare specific amount of ingredients and cooking. Only by measuring and comparing the quantity of the ingredients can you get the accurate proportion of each and prepare food as described in the recipe. Therefore to cook as accurately as you can, the principle of stoichiometry can be applied in the kitchen.
