Cream of Tartar and Baking Powder

Cream of Tartar

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.

The properties of this natural additive help you make the best meringues, biscuits and cookies. It’s also suitable for vegetarians and coeliac sufferers as it contains no gluten!

How often have you tried to make a meringue and failed to get the volume and stability necessary? Using cream of tartar in the amount specified in the recipe you are following helps you get the best meringue that you have ever made. Finger-licking good!

The key of this powerful natural ingredient is its function of increasing the volume and stability of whipped egg whites in meringues and soufflés, as well as in other culinary techniques. For example, recipes such as Angel Food Cake or Chiffon Cakes always add a touch of cream of tartar.

The main uses of cream of tartar are:

  • Natural raising agent: the basic ingredient of any natural raising agent.
  • Pastries: used for preparing meringues, soufflés, cookies and many more.
  • Pharmaceutical industry: has an effect as a diuretic and laxative.
  • Complement for sweeteners: eliminates the after-taste of some sweeteners.
  • Wine making: tartaric stabilisation. Basically used to reduce the cooling times for wine to less than 24 hours.

And now you know about the uses of cream of tartar, why not buy it in NaturalCastelló and start making your recipes?



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.
We are 100% sure that cream of tartar will never be absent from any pastry bakery.


Angel Food Cake

For Angel Food Cake containing 9-10 egg whites, we recommend adding 1 heaped teaspoon of cream of tartar.


Chiffon Cakes

In this case, we recommend 1 teaspoon of cream of tartar for a preparation with 7 eggs.

Gluten-free baking powder has become one of the indispensable products for the larder of any coeliac sufferer, but also for anyone who does not suffer from intolerance to gluten derived from wheat, barley, rye and oats (and all their varieties). Analysing the situation of gluten carefully, we come to the conclusion already confirmed by thousands of nutritional experts all over the world, that gluten is not an essential protein for human beings.

Unfortunately, there are many foods that contain gluten and so coeliac sufferers must especially check the labelling of everything they eat.
