Prep time includes resting/rising. Also a copycat of Pappa Roti. These are delicious and so different- Not really Mexican, they are from Malaysia. It is like a thin coffee butter cookie spread over the bun. When you bite into these the outside is crisp while the inside is soft and buttery. I have been told you can freeze the cooked buns and heat in an oven for 10-12 min.(never tried this)--the texture does end up being more chewy/dense after the first day (still tastes good)--so I halve the recipe if I know they won't get eaten by the next morning. Or refrigerate half the dough to use the next day. The outer crust will go soft after a while--if the buns are room temperature, heat in oven for about 4-5 minutes and then take out and wait a minute or two and it crisps up again. You may need extra bread flour in the final dough when kneading if too sticky...add a TBS at a time. This recipe is converted from metric to US measurements so it is not always easy to get exact.
