Calcium Hydroxide Method (Nixtamalization)

This is a method of converting pectin into calcium pectate. This can be used on a wide variety of fruits and vegetables. It is most commonly known as Nixtamalization.

Ingredients

• .5 grams food grade Calcium Hydroxide (Ca(OH)₂)

• 200 grams dechlorinated water (you can dechlorinate tap water by bringing it up to a boil and letting cool down to room temperature)

Steps

1. in a non-reactive bowl or container, combine calcium hydroxide and water by stirring with a spoon, or whisk

2. add fruit or vegatable into a non-reactive storage container and pour calcium hydroxide solution over. make sure all items are fully submerged

3. leave sitting at room temperature for 12-24 hours

4. remove fruit or vegetable and rinse under cold water thoroughly

5. dry and use in various applications

Applications

Raw

Foods that have been soaked in a calcium hydroxide solution can be eaten raw. With their pectins converted into a more stable calcium pectate. These items can be more colorful and maintain their shape. Texturally these foods can feel denser.

Dehydrated

By placing foods into a dehydrator or low oven (between 120ºF-200ºF) anywhere from one hour to twenty four hours, you will find foods that have a very concentrated interior while the exterior can become chewy, like a fruit leather. This application on tomatoes yields something similar to sun dried tomatoes.

Boiled

Cooked

This technique is widely variable and you must experiment with and assess results to find the right applications for yourself.

¹ On the usage of the word “nixtamal” and “nixtamalization.” I am aware that nixtamal is deeply cultural and much more than just a chemical process. I have never made a tortilla, or travelled to central or south America. I am choosing to use the word nixtamalization throughout my recipes because I believe it is the most commonly understood word to describe this process. It is not my intention to repurpose or appropriate this deeply cultural method. I do intend in due time to travel and learn how to make a tortilla. Thank you.
