A mixture of pectin, an edible mono- or disaccharide, an edible organic acid, an edible salt of an organic acid, and at least one further ingredient of the group consisting of fruit pulp, fruit juice, syrup, flavoring agents, coloring agents, and water, when sterilized and maintained under sterile conditions, has a long storage life and is quickly converted to an edible gel at ambient temperature by mixing with an edible source of calcium ions, such as milk. For a gel of pleasant taste and texture, the initial mixture should contain, per gram of pectin, 2.5 to 30 g of the saccharide, 0.15 to 0.75 g organic acid, 22.3 to 85 g water. It should further contain 1 g to 1.5 g of the organic acid salt per gram of the organic acid, and enough of the acid and salt to make the pH of the mixture 3.0 to 4.3. 25 to 40% of the carboxyl groups in the pectin are to be esterified with methanol.
