Smoked Gouda Triscuits and Grooves Sharp Cheddar (either color) and regular Cheez-Its don't need toppings. But toppings are nice, too. I usually go for some sort of cheese (many that I like).
i reject your premise. I don't really eat crackers, but when I do, I like Carr's table water crackers with aloutte garlic and herbs spread, preferably with a smoked oyster on each.
