Which conditions are required for high‑methoxyl pectin to form a gel when making traditional jam?

Options:

High sugar content and low pH (acid)
High temperature alone
Extended refrigeration at low temp
Addition of calcium ions

Correct answer: High sugar content and low pH (acid)

Explanation: High‑methoxyl pectin needs sufficient sugar and an acidic pH (typically below ~3.5) to gel; calcium ions are used for low‑methoxyl pectin systems instead.
