1 french bread baguette, halved
1/4 cup softened butter
1/3 cup mayonnaise
1 tsp hot sauce or to taste (I use whatever I've got. He prefers Crystal, of course.)
4 cloves garlic finely minced or, better yet, pressed into paste.
1/2 cup grated cheeses: parmesan, mozzarella, cheddar, whatever... I find that a finer grate is better.

Adjust to taste. Sizzle garlic in cold pan with tsp of water and a tbsp of butter until the paste is slightly darkened and caramelized. Mix all the ingredients together and spread. Wrap in foil and bake in a preheated 400 degree oven for 10 minutes. Open up the foil and broil on a baking sheet in the lower rack of the oven till bubbly golden.

Or,

Mix, spread and broil. Coolio style.
