Here’s a must-have you’ll need to preserve the texture and flavor of all things crispy! Tupperware’s One Touch range is a superstar when it comes to sealing in the crunch thanks to its virtually airtight design. It also comes in assorted sizes so you can store away all kinds of food, no matter big or small. To open, just press center and lift lid. To close, press down the center. Best of all, it’s space saving too so you can store them away neatly for the next time you’ll need them! Canisters fit snuggly inside one another to save space. Extra Tip The One Touch is great at keeping clumps at bay in flour and other powdered form ingredients too.
