This is one recipe that can be used when one has a potato omelet left over from the previous day but it is so good that you will make sure there is leftover tortilla. The sauce will also make the omelet stand out when guests are coming for dinner.
Ham and sorrel is a perfect match, with a flavor suggestive of a spring evening. Use Serrano if possible, in which case skip the salt, as Serrano ham has plenty.
These are omelets fit for a summer party. Applying a little imagination to the fillings, it is possible to take advantage of almost any kind of leftovers.
The basic ingredients for a Spanish omelet are eggs, potatoes, olive oil, the optional onion, and salt. To be truly a Spanish omelet, the potatoes should be sliced and cooked in oil, this brings out the best of flavor.
