yeasty

It is as yeasty as a dinner roll, and cut to form a pocket with closed ends that shore in all ingredients.

At his feet, on the sand, lay great tangles of kelp and flecks of yeasty froth.

Then in huge waves hundreds and hundreds of feet high, the ocean flowed in and all was troubled, yeasty sea.

Several died, and there were burials at sea, when the plank was tilted and the body slid into the yeasty deep.
