In a bowl, mix the flour, salt and baking powder.
Add the olive oil and boiling water and mix. First, use a spatula to prevent getting burnt. Once the spatula isn't helping anymore, switch to your hands.
Knead until the dough comes together, about 2 min.
Let the dough rest, covered and at room temperature, for 1 hour.
Weigh the dough and divide it into 8 portions.
Flatten each portion with the palm of your hand and then fold the edges in, like making a parcel. Turn it over and roll it on the surface to close the seam.
Flatten out each ball with a rolling pin until very thin. You should be able to see through it.
Preheat a pan to high heat and give it at least 5 minutes. It should be smoking.
Add one tortilla at a time and cook for 1 minute per side. It's completely normal if they inflate.
If not used in the next 2 hours, refrigerate in an airtight container for up to 5 days. You can also freeze them for up to 3 months in an airtight container or bag, separated by baking paper.
