We all remember our mothers telling us to finish everything on our plate and not to waste any food. This is all the more important in the present day context where there are millions of people who do not have even one proper meal a day. Every time you throw away food, think of the less fortunate and make an effort not to waste.
Plan your meals
Have a meal plan for the week and base your weekly grocery list on this. With experience you will know the quantities needed for your needs and only purchase the necessary quantities. If you want to try out exotic recipes, buy the ingredients which will not be used in your regular cooking in the smallest quantity available.
Be a smart shopper
Do not buy excessive quantities of a product just because it is on special. Without realizing it will be past the use by date
Use leftovers
Leftovers can be used as an ingredient to prepare another dish or as part of the next meal. Do not throw them away.
Store food properly
Make sure the food is properly stored in suitable containers to maximize its use, such as wrapping meats properly before freezing to prevent it from drying.
