Eggless Mayonnaise

This is a very old recipe for a Spanish/Portuguese condiment recently highlighted by David Leite, the founder of Leite's Culinaria, in his book, "The New Portuguese Table." David learned the recipe from Ilda Vinagre, a chef in Portugal (who, in turn, had learned it from a cook in Brazil). It is silkier and lighter than regular mayonnaise, tasting a bit like olive-oil-whipped cream. Great for those who cannot eat eggs and miss the mayo in their sandwiches!
