Surprise rainstorms or lack of outdoor space don’t have to ruin your grilling plans, thanks to portable miniature indoor grills. Before buying one, though, you should consider a few things: First, do you want an open grill or a contact grill? With an open grill, you’ll need to flip the food to cook both sides, but you can prepare a wider variety of food. Contact grills come with a floating cover that cooks the top of the food, so there’s no need to flip. (They can also function as panini sandwich makers.) Once you’ve settled on a type of indoor grill, do you want one with adjustable temperature (some have only one setting: on), and how much grill space do you need? Here are three options to keep in mind.
