Can you use expired yeast

Keep fresh yeast in its original packaging inside your fridge, where it should last for weeks. Or place it in a zip-lock bag and store it in the freezer for months.

As a rule of thumb, buy fresh yeast only if you intend to use it within the next days. In theory, nothing is really stopping you from making a dough with expired yeast. Doing so helps you ensure that the yeast cells are living and will therefore make the dough rise. What was your experience? Did it end up working out for you?

When the acid comes into contact with the baking soda, it'll create a chemical reaction, which produces carbon dioxide bubbles, and it's those carbon dioxide bubbles that will make the bread rise.

For this substitute to work properly, you need to add your baking soda and acid after all other ingredients have been added to the recipe. Baking soda is a single-acting leavening, so it's important to get your baked good into the oven soon after you've added it.

Replace the yeast called for with an equal amount of baking powder. Since baking powder contains both baking soda and acid cream of tartar , it contains everything needed to make your baked goods rise. Baking powder is double-acting, meaning it causes two rises: the first when you add it to your recipe, and the second when it's heated in the oven. Because of this, you don't have to wait until the end to add it, as you do with baking soda.

Just throw it into the mixing bowl with the rest of your dry ingredients, and continue on with your recipe. If your recipe already calls for baking soda, baking powder, or one of the acids mentioned, your substitute needs to be added in addition to the amount already called for in the recipe.

Some time before anything goes mouldy, it may go a bit grey if it started out green or just a murkier version of itself if it started out red. This is plain pigment oxidisation and is not dangerous, though it is a bit unappetising — if the fat has oxidised, you will be able to smell it.

Baking powder and bicarbonate of soda typically have shelf lives of one to two years, but storage is more important than numbers, and there is a school of thought that says bicarb lasts for ever. Yup, for ever. A whole bird has a much smaller surface area.

Salt, naturally, has a preservative effect, and the sniff and overall appearance test should work with things such as salami. So there is something to be said for using your memory rather than your judgment. The food safety scene is united on this — nothing with mould should be consumed, except where it has been introduced deliberately blue cheese.

Millstone is slightly forgiving on this. But if the entire top surface is covered in mould, you should discard it. Again, frozen, tinned and dried food gets a BBE date rather than a use-by date.

Do yourself a favour, though, and taste these things if they are very old.
