PROJECT KANTEN

This project is about cooking with KANTEN, a shelf-stable foodstuff with remarkable gelling properties. It is used to make a wide variety of sweet jellies and savory aspics.

Kanten is sold as sticks (they look a  bit like brittle cellophane or styrofoam) and in powdered form (most often packaged in pre-measured packets).

One stick of kanten can gel about 1 and 3/4 cups liquid (500ml); one packet of kanten powder (about 4 gr or 1 teaspoon) gels slightly less — about 1 and 2/3 cups liquid (450ml). A great deal depends upon the chemistry of the specific liquid. Interestingly, fresh pineapple (that does not gel with animal-sourced gelatin) will solidify nicely with marine-sourced kanten.

Stored in an airtight container, kanten sticks and/or powder will keep, dried, indefinitely.

 

JELLIES & ASPICS: Fruit & Vegetable, Sweet & Savory

In recent years the beverage industry has brought mixed fruit and vegetable juices with no added sweeteners or coloring agents to market. Introduced as a grab-on-the-go boost to nutrition, most are packed with vitamins and minerals (check labels before buying).

These juices are perfect for quick-crafting colorful, healthy desserts. Some of my favorites are mixed berries, mango-apple and tomato-veggie combos. I also like to make savory aspics with cold noodles and veggies using dashi as my liquid.

In addition, coffee and tea can be made into jellies, too, though to get a stiff gel you’ll need to add a bit of sweetener (a pinch of sugar or a drop of agave or other syrup).

Because kanten itself has zero calories and is 80% fiber, it’s a simple way to make cool, easy-to-eat treats for hot weather.
