Claims: What is claimed is:

1. A method of preparing a precursor for an edible gel which comprises:

(a) mixing pectin, an edible saccharide, an edible organic acid, an edible salt of an organic acid, and at least one member of the group consisting of fruit pulp, fruit juice, syrup, flavoring agents, coloring agents, and water,

(1) the amounts of the mixed pectin, saccharide, acid, salt, and at least one member being such that the resulting mixture contains, per gram of said pectin, 2.5 to 30 g saccharide, 0.15 to 0.75 g organic acid, and 22.5 to 85 g water, and

(2) the weight ratio of said acid to said salt is between 1:1 and 1:1.5 and sufficient to make the ph value of said mixture 3.8 to 4.3,

(3) 25 to 40% of the carboxyl groups in said pectin being esterified with methanol;

(b) sterilizing said mixture; and

(c) maintaining the sterilized mixture under sterile conditions.

2. A method as set forth in claim 1, wherein said saccharide is a mono- or disaccharide.

3. A method as set forth in claim 2, wherein said edible organic acid is citric, tartaric, malic, or lactic acid, and said salt of an organic acid is an alkali metal salt of citric, tartaric, malic, or lactic acid.

4. A method as set forth in claim 1, wherein said mixture is sterilized by heating at a temperature of 100.degree. to 75.degree. C for 10 to 60 minutes.

5. A method as set forth in claim 4, wherein said mixture is heated at said temperature while sealed from the ambient atmosphere, and kept sealed from said atmosphere for said maintaining under sterile conditions.

6. A precursor composition for an edible gel, stable during extended storage and comprising:

(a) an airtight container; and

(b) a sterile aqueous mixtue hermetically sealed in said container, said mixture essentially consisting of pectin, an edible mono- or disaccharide, an edible organic acid, an edible salt of an organic acid, and at least one member of the group consisting of fruit pulp, fruit juice, syrup, flavoring agents, coloring agents, and water,

(1) said mixture containing, per gram of said pectin, 2.5 g to 30 g of said mono- or disaccharide, 0.15 to 0.75 g of said organic acid, and 22.3 to 85 g water,

(2) the weight ratio of said acid to said salt being between 1:1 and 1:1.5 and sufficient to make the pH value of said mixture 3.8 to 4.3,

(3) 25 to 40% of the carboxyl groups in said pectin being esterified with methanol.

7. A method of preparing an edible gel from the precursor composition set forth in claim 6 which comprises:

(a) opening said container; and

(b) combining said mixture with an edible source of calcium ions in an amount sufficient to cause gelling of the combined mixture and source.

8. A method as set forth in claim 7, wherein said source is a calcium-bearing, aqueous, colloidal dispersion of a protein.

9. A method as set forth in claim 8, wherein said dispersion is a milk of a mammal.

10. A method as set forth in claim 8, wherein said protein is soybean protein.
