Eggs are delicate. The egg shell may have as many as 17,000 tiny pores over its surface. Through them, the egg can absorb flavours and odours. Keep them pointed end down in their cartons to help keep them fresh.
Current legislation requires a best before date appear on the carton. We calculate 5 weeks from the week of production to the best before date. Try to avoid washing your eggs until ready to be used. And best of all take them out of the fridge 30 minutes before use to allow them to reach room temperature.
Egg whites will keep up to two days in the fridge or can be frozen. Thaw when needed and make sure to use them the same day. Eggs yolks can be kept in refrigerated and covered with water for one to two days at most.
