The bigger a party’s guest list, the harder it is to accommodate every guests’ tastes. Maybe that guy doesn’t like spicy foods. Maybe that lady has a gluten allergy. Maybe that other guy is vegan. It’s gonna be hard to find finger foods that every single guest can jive with, but as the guest list increases, a need for detail decreases. It becomes less about finding what tastes the best and more about what everyone can agree on. In times like these, simple is best.
For a few lightning-round ideas, roast some simple veggies like broccoli, carrots, and cauliflower in the oven and serve with some light dipping sauce. Mix together some nuts, pretzels, and dried fruits to make your own party snack mix. Get some simple shrimp for shrimp cocktail, but lay out a whole lot of different sauces to get your variety.
The point is that you don’t need a cookbook to make snacks. Dietary restrictions aside, you can usually just make whatever you think tastes good, and as long as it’s presented well, your guests will eat it up without a second thought. Long as you don’t have weird tastes and eat, I don’t know, squid marinated in peanut butter, it’ll work out fine.
