From Cookipedia(Redirected from Jelly-bag)
A jelly bag is a cloth or nylon bag which is often suspended on a stand to allow excess liquid to drain from foodstuffs separating liquids and solids. This process relies on gravity and is often left overnight to complete. By not squeezing or forcing the straining foodstuffs, the resulting liquid is relatively free from small impurities, therefore clear. As it's name implies, it was originally used in the process of making jellies jams and preserves.
