A kitchen torch is a handy tool that has a variety of uses. It can caramelize sugar on a creme brulee, melt cheese on gratins, brown marshmallows for s'mores and even sear steaks. You can buy one online from a number of retailers including Amazon, Sur La Table and Wayfair. There are a variety of different models available, so it's important to consider what you plan to use the torch for before making a purchase. Many models include a removable butane canister, while others attach to an external propane tank and feature a convenient fuel gauge on the handle to let you know when it's time to refuel.
If you're new to using a culinary torch, it may be best to start with an affordable model that comes with a refillable canister of butane. These are typically smaller and easier to control than models that attach to a gas canister, but they're still powerful enough for a range of applications. Many of these models also include a safety mechanism that prevents the flame from coming near your hands, making them suitable for beginners who are concerned about handling such a powerful flame.
Once you have a reliable kitchen torch, it's a good idea to stock up on butane so you'll always be ready to use it. You can find butane online at Amazon and at stores like Home Depot and Lowes, as well as at drugstores and supermarkets. It's important to buy butane that matches the brand of your torch, as lower-quality butane can quickly ruin your appliance.
