If you watched my video on making Tortilla Quiche for a weekend lunch, you saw me recommend a fluted baking pan that can be used to turn a flour tortilla into an edible bowl. I also mentioned that you can get a similar result by using an oven-safe mug, or a muffin tin.
Now there’s another option. Productivity blog Lifehacker recently posted an article showing how you can make these tortilla bowls by using your muffin tin upside-down. If you are following the Tortilla Quiche recipe, you may want to try baking the tortilla by itself for a few minutes first, just to make sure it holds its shape once you add the egg mixture.
