Make Sufganiyot. In large bowl, stir warm water, yeast and a pinch of the granulated sugar until yeast dissolves; let stand a few minutes until yeast bubbles. (If yeast doesn’t bubble, throw out mixture and start over.) Stir in remaining granulated sugar, 2 1/2 cups of the flour, the salt, cinnamon, warm milk, oil and eggs until well mixed. Gradually stir in more flour until dough is firm and smooth.
