To Buy:
Buy in blocks from the supermarket. Lightly salted butter is used for general cooking, and unsalted butter for baking.
To Store:
You can store butter (opened or unopened) up to one month in a refrigerator. Opened butter should always be put in a separate refrigerator compartment or in a covered butter dish to prevent them from absorbing other food odours.
Tips & Tricks:
Butter contains 4 grams of fat per teaspoon. Enjoy it in moderation and try to limit intake by spreading it soft - so it goes further. Cool your toast before spreading butter on it. Use olive oil over cooked veggies instead of butter and avoid any bread and butter at night.
A serve of butter is calculated per teaspoon.
Cooking Tips:
For baking, nothing really beats butter - use sparingly as a treat.
