This flexible chocolate recipe is from my dear friend John from Molecular Culinary Academy. The use of locust bean gum and kappa carageenan gives it a little bit of stretch and flexibility. I used it in the plated dessert shown above, created for a demo for the culinary program at Canadore College many years ago.
Carrageenan is a hydrocolloid derived from seaweed that yields a firm, brittle gel that sets quickly. There are two two types: Iota and Kappa. Iota sets softer and more elastic, while kappa yields a firmer and more brittle result. Typically, carrageenan is mixed into cold liquids and begins to set with heat. Use at roughly 0.25%. In the presence of any milk-based product, it will set much firmer due to its reaction with lactic acid. Another of its many unique properties is that will also set firmer when combined with a locust bean gum, which is why it is often used in conjunction with carrageenan.
