My annual public service:
The REAL Original CHEX Party Mix
1 stick (1/2 C) butter or margarine
1 1/4 teaspoons seasoned salt
4 1/2 teaspoons Worcestershire sauce
2 1/3 cups Corn Chex
2 1/3 cups Rice Chex
2 1/3 cups Wheat Chex
1 cup small pretzels
1 cup salted mixed nuts
Heat oven to 250. Melt butter in 15x10x2 pan; remove pan from oven.
Stir in seasoned salt and Worcestershire sauce.
Gradually add cereal, pretzels, and nuts, stirring to coat evenly.
Bake 1 hour, stirring every 15 minutes.
Spread on paper towels to soak up excess oil.
N.B.: The recipe on the present day cereal boxes is touted as "original" but contains ingredients that weren't around in the 1950s like "garlic flavored bite-size bagel chips."
