This very rich Mexican candy is something like a giant peanut butter cup made with dark chocolate and slightly grainy, freshly ground peanuts. As the name indicates, it is a Mexican adaptation of marzipan, substituting peanuts for ground almonds.

Grind peanuts fine in food processor. Add sugar and process into compact paste. Divide into 12 equal pieces. In 2 1/2" diameter ramekin, mold each piece into thick disk. Remove disks from mold carefully.

Melt chocolate in double boiler and keep warm. Spoon 1 generous tablespoon melted chocolate into wax paper. Carefully place 1 peanut disk on top and move around to cover entire bottom of disk with chocolate. Then enrobe top and sides with melted chocolate. Repeat process to enrobe remaining disks. Place candies, still on wax paper, in refrigerator until ready to serve.
