The temperature is the problem. Yeast requires a consistent ambient temperature of 24-27°C to activate properly. A cold kitchen will significantly slow or halt this process.
Here are two efficient methods to create a controlled environment:
1. Oven Method: Turn your oven on to its lowest possible setting for 2-3 minutes, then turn it off completely. Place the dough, in a covered bowl, inside the oven. The residual warmth is sufficient for proofing. Some ovens have a dedicated "proof" setting which is ideal. Alternatively, simply turning on the oven light can provide enough warmth.
2. Multicooker Method: If you own a multicooker (e.g., an Instant Pot) with a "Yogurt" function, this is the most reliable option. Place a piece of parchment paper or a silicone liner in the bottom of the pot. Put the dough inside, and select the "Yogurt" setting on the "Less" or "Low" temperature. It provides a perfectly controlled, consistent heat for rising.
