When shopping for a new sandwich press there are a variety of factors you may wish to consider.
Sandwich presses generally come in two main sizes that will fit either two or four slices of bread. Keep in mind that the larger models are not just for cooking more food at once, but often add versatility by being able to accommodate a wider variety of breads, rolls and buns.
Whichever size you decide on you should always check you have enough room for the appliance both on the countertop and in your cupboards. Look for easy storage designs like a latch that will lock the top and bottom plates shut together and a space to wrap the power cord underneath the appliance.
Some models can adjust the height of the top plate and lock it in place at various heights, like some of the Breville sandwich press models. This is great for cooking larger sized sandwiches and open melts. This feature is also useful for adding and removing food to the hotplates without having to hold the top plate up, so you can take more care with placing larger food items.
