Thickener for liquid component

A method of producing a thickened composition, comprising:

• a mixing step of mixing a thickener and a liquid component,
• wherein the thickener contains an oil and/or fat composition, and
• when a total triglyceride content is set to 100% by mass, the oil and/or fat composition contains
• 65 to 99% by mass of one or more types of XXX-type triglycerides having fatty acid residues X, each with x carbon atoms, at positions 1 to 3 and
• 35 to 1% by mass of one or more types of X2Y-type triglycerides each having a fatty acid residue Y with y carbon atoms in place of one of the fatty acid residues X of the XXX-type triglyceride,
• x, the number of carbon atoms, is an integer selected from 8 to 20, and
• y, the number of carbon atoms, is each independently an integer selected from x+2 to x +12 and satisfies y≤22, and
• wherein the liquid component is a liquid at 20° C.
