Cream of tartar often appears in home-made pastry recipes but many people still don’t know what it is. So here we are going to explain what exactly is this very important ingredient for baking and what can it be used for.

Before buying cream of tartar, what is it?

Cream of tartar is the popular name given to potassium bitartrate, potassium hydrogen tartrate, tartaric acid salt or E336(i). This ingredient is a white and fine powder in appearance. It has no flavour and performs the function of a chemical raising agent. It is particularly used in making cakes but it can also be a corrector of acidity in wines or an essential ingredient in making fizzy or carbonated drinks. It can also be found in sweets, jams, sauces and dehydrated soups!

Cream of tartar is clearly not a relatively new component as it was isolated by the Swedish chemist Carl Wilheim Scheele in 1769. Before then, it was known in its natural form in plants, but especially as a by-product of grapes. Thus cream of tartar originates from the natural crystalline acid that is deposited on the walls of wine cellars. At this stage it is known as tartar, and after a production process when it is turned into a white powder called cream of tartar, it can be used for various culinary processes.

To make a home made meringue, we recommend 1/8 of a teaspoon per each egg white. This will give the volume and stability that you need for your meringue.

Home raising agent

For a home raising agent, we recommend using two parts of cream of tartar for one part of sodium bicarbonate.

Whipped cream

Add cream of tartar as specified by the recipe.

Dough and bakery preparations

Cream of tartar is a perfect natural ingredient for making doughs with greater volume. In fact, it is considered as the best chemical raising agent for the bakery, together with sodium bicarbonate. Both ingredients start to work from the moment they come into contact with the damp dough.

Professional pastry chefs also use this ingredient for adding toppings to sweets, achieving more creamy textures, preparing creative fondants or preventing crystallisation of sugar or caramel.
