If using fresh or active-dry yeast, place half cup of flour with a tablespoon of sugar (both subtracted from the total amount), half the milk and the yeast in the bowl of a stand mixer (KitchenAid or similar). Mix a little and let stand 5-10 minutes, until bubbles start to appear. If it has no activity, the yeast is probably old. Buy new and start again.
Add the rest of the flour and sugar to the bowl with the yeast mixture. If using instant yeast, place 2 cups all-purpose flour and ¼ cup sugar in the bowl and add the yeast. Stir to mix.
Incorporate 1 egg, ¼ cup whole milk, ½ tablespoon liquid honey, ½ teaspoon vanilla extract and ½ teaspoon lemon zest. Start kneading and sprinkle in ½ teaspoon salt. Knead for 2 or 3 minutes, until all the ingredients start to combine.
Add ¼ cup unsalted butter in three or four parts, waiting about 20-30 seconds between each addition. Continue kneading until a smooth and soft dough is formed, about 8 to 10 minutes. It is very elastic and hardly sticks to the fingers.
Form a ball, cover with a clean kitchen towel, and let it rest for 15 minutes. I do so on the kitchen counter, but you can use a bowl.
Have ready a lightly buttered or parchment-lined baking sheet.
Once the dough has relaxed, form a log with it and then a ring, sinking the center with your hand and opening it (as you would a bagel), until you can place an upside-down small glass or ramekin or a scone ring in the center to keep the circle open. Make sure they’re oven-safe, metal or ceramic, as it will go with the dough into the oven.
Place the ring on the prepared baking sheet with the glass or ring in the center. cover, and let the dough rise in a warm place for approximately 1 hour.
