Achieving the perfect rise is essential for creating fluffy Apricot Jam Buns. The first step is to activate your dry yeast properly by mixing it with warm milk (ensure it's lukewarm, around 37-38 degrees Celsius) and a bit of sugar. This activates the yeast, allowing it to foam and bubble, indicating that it's alive and ready to work. When combining your ingredients, knead the dough thoroughly until it is smooth and elastic, which helps develop gluten and traps air, promoting a good rise. Cover the kneaded dough with a clean kitchen towel or plastic wrap, and let it sit in a warm, draft-free area to rise. Ideally, this should take about 1-1.5 hours or until the dough has doubled in volume. For the second rise, after shaping the buns, ensure they are spaced adequately on the baking sheet and again cover them as they rest. This final rise typically takes about 30 minutes and is crucial for achieving the right texture.
