Old Bay Grilled Shrimp

Making one’s own Old Bay is a cinch: just mix together mustard seed, celery seed, a little coriander seed, and thyme (powder these up) with paprika, salt, and a pinch of pumpkin pie spice (mine is a combination of cinnamon, clove, star anise, fennel seed, allspice, nutmeg, and mace). The leftover shrimp made an outstanding po’boy.
