The Blendtec Twister Jar is suitable for all blenders from Blendtec. You can use these especially for making thick mixtures such as peanut butter, hummus, smoothies and baby food. The strong, flat blade of hardened steel cuts effortlessly through thick masses, such as bread dough or cookie dough. The lid has a handy filling opening, so that you add extra ingredients during blending. The blender jar has a capacity of 1 liter and is made of tritan, a plastic that is resistant to heat. This also adds warm ingredients. Is your homemade peanut butter ready? Then use the supplied flexible spatula to get the bottom out of the can.
