Arepas de Huevos
When cutting the hole, make sure the knife stays inside the arepa so the egg doesn't leak out. If the arepa hasn't puffed up completely, you can use the knife to open it up a bit more. You want enough space to pour the egg into. If it appears like you won't have enough time to repair the hole after adding the egg, you can place the arepa into the oil on edge (with the hole facing up) to let the egg set a bit before letting it completely submerge.
We have determined the nutritional value of oil for frying based on a retention value of 10% after cooking. Amount will vary depending on cooking time and temperature, ingredient density, and specific type of oil used.
