Direct milk in a slow cooker

Overview

The slow cooker's crock becomes a small cheese vat or yogurt pot. The base heats, the cook watches the probe, and lifting the crock or switching off ends the heating.

A demonstration by Kathy Love uses the crock in this way to make mozzarella. A current yogurt method uses the same appliance: it heats to 82 °C, switches off, and lets the milk fall to 43 °C over 2 to 3 hours before inoculating.

How it works

The milk touches the hot ceramic wall directly, so it needs stirring while it heats and stillness during a rennet set. Lifting the crock removes the element but not the heat stored in the wall, which keeps warming the milk for a time. The yogurt method uses that stored heat on purpose.

Documented and proposed uses

Quick acidified mozzarella: High to 95 °F, lift for rennet, back on High to 105 °F, then lift. The demonstration records these targets only.

Yogurt: High to 82 °C, switched off, and wrapped in a towel while it incubates.

Paneer (proposed, an adaptation): direct heating to 85 to 90 °C with stirring, transferred from the stove method.

Measuring

Measure the milk temperature against time, with the probe position noted, especially in the minutes after each lift or switch-off. Record the time to each target and any milk solids stuck to the crock.

Limits

The demonstration records only the targets reached (95 °F and 105 °F), not the overshoot after each lift. It is one cook, one cooker and one batch, with no quantities.

Unsuitable for holds that need a narrow culture range, such as quark's falling 68 to 71 °F set.
