Mary Jane’s recipe is based on one by the Barefoot Contessa (Ina Garten), but the shoeless TV cook wouldn’t dare to use red chile powder! You will need a springform pan for this cake since it would be difficult to get it out of a regular cake pan in one piece. You can use semisweet chocolate instead of bittersweet in the filling and the cake will be slightly sweeter. Maybe a scoop of ice cream on the side when you serve it to guests?
This traditional tapa is not anything like a Mexican tortilla. A Spanish tortilla is a large, thick, omelet-like cake made with potatoes and eggs and is served at room temperature. Romesco sauce is an all-purpose Spanish sauce that is served with a wide variety of dishes. From the Tarragona region, this Catalan sauce combines two of the most popular horticultural imports from the New World---chiles and tomatoes. The sauce gets its name from the romesco chiles that are used but are not readily available outside of Spain. The combination of ancho and New Mexican chiles approximates the taste.
