Baking sweet potatoes and then putting them in an ice bath has been a total game-changer. This method involves baking, an ice bath, and then a second bake to finish them off. I’ve experimented with different temperatures and times, and this combination worked best for me. Try this sweet potato ice bath method for a creamy, caramelized sweet potato!
How Does it Work?
First Bake: The starches begin to break down. The enzyme amylase is activated at moderate heat and converts starch into maltose. This is why sweet potatoes taste sweeter when baked slowly.
Ice Bath: This rapidly cools the sweet potatoes, helping set the structure of the softened starches. It prevents overcooking and locks in moisture.
Second Bake: Since the starch has already converted to sugar, the higher heat helps caramelize the sugars. This creates a creamier, custard-like texture.
