Build a shopping list around the meals you will actually make
Choosing three recipes does not tell you how much to buy. Meals eaten out, guests and ingredients already at home change the calculation. Turn your meal ideas into useful quantities before filling your basket.

Count who will be there
List only the meals you need to prepare and the people expected at each one. Two people at three dinners means six dinner servings, not six different recipes. Put uncertain meals in a separate column so you can plan a simple option without buying an entire extra menu. This count organises shopping; it does not define anyone’s nutritional needs.
Include tomorrow’s lunch explicitly
If you want a serving to take away the next day, add it to the plan. Dinner for two plus one packed lunch means three planned servings. Write that instead of “make a little extra”, then adjust for appetites and side dishes. Follow food-specific storage and transport guidance; this planning method does not establish a storage time.
Convert servings into quantities
Use the recipe yield as a starting point. Fictional example: if four servings require 300 g of an ingredient, three servings give 300 × 3 ÷ 4 = 225 g. This illustrates arithmetic, not a recommended nutritional portion. Add salt, spices and some liquids gradually. Cooking time does not scale mechanically with ingredient amounts.
Combine matching ingredients
Once each recipe is scaled, group identical ingredients. Requirements of 225 g and 150 g add up to 375 g. Keep units consistent: do not mix grams, item counts and volumes without checking. Separate products serving different purposes, such as fresh tomatoes for salad and chopped canned tomatoes for sauce.
Subtract what is already available
Check actual usable supplies. A requirement of 375 g minus 100 g available leaves 275 g to buy. If the pack is larger, note the surplus and a possible use. Avoid adding a complicated recipe just to justify a large pack; a smaller size or an ingredient already planned may suit you better.
Finish with three columns
Use total needed, already available and to buy. Add a short use note for opened products or pack sizes that leave extras. Keep the list with your meal plan so each purchase has a clear purpose.
