Activate Yeast: In a bowl, dissolve yeast and sugar in warm water. Let sit for 5–10 minutes until frothy.
Mix Dough: Add coconut milk, flax egg (if using), salt, and 1½ cups flour. Mix, then gradually add the remaining flour until a soft dough forms.
Knead: Knead on a floured surface for 10 minutes until smooth. Perform the windowpane test by stretching the dough thinly without tearing.
First Rise: Place the dough in an oiled bowl, cover, and let rise in a warm spot for 1 hour, or until doubled in size.
Shape: Punch down the dough. Divide into 8 balls. Roll each into a 5-inch circle. Brush with vegan butter, fold in half, and seal the edges.
Second Rise: Arrange on a greased pan, cover, and let rise for 30 minutes.
Bake: Preheat oven to 375°F. Place a pan of water on the bottom rack. Bake the rolls on the top rack for 12–15 minutes, until golden.
Glaze: Brush with coconut milk while warm.
Serving Suggestion: Serve with jerk chicken, callaloo, or a Jamaican beef patty.
Storage: Store in an airtight container for up to 2 days, or freeze for up to 1 month.
