Cultural Tip
In Brazil, both fresh (baker’s) yeast and dry instant yeast are common. Bakers often ‘prove’ dry yeast by mixing it with warm water and a pinch of sugar; if bubbles appear within 10 minutes, the yeast is active. Fresh yeast can be tested by crumbling a small piece into warm water – it should dissolve and become frothy. Knowing how to check yeast activity saves time and prevents flat breads.
