Spicy mayonnaise: Place all ingredients except oil in blender. On medium speed, slowly add the oil to emulsify into mayonnaise. **RAW EGG WARNING The American Egg Board states: "There have been warnings against consuming raw or lightly cooked eggs on the grounds that the egg may be contaminated with Salmonella, a bacteria responsible for a type of food poisoning....Healthy people need to remember that there is a very small risk and treat eggs and other raw animal foods accordingly. Use only properly refrigerated, clean, sound-shelled, fresh, grade AA or A eggs. Avoid mixing yolks and whites with the shell." Tempura batter: In a mixing bowl, blend the dry ingredients. Stir in the egg, and while stirring, pour in the seltzer, 1/2 cup at a time. Stir to completely combine ingredients. Add enough seltzer so that the blend is the consistency of unwhipped heavy cream. Stir in a few ice cubes to keep the batter very cold.
