Test Kitchen Tips:

  • If you have a slow cooker with stove-top safe cookware, substitute the cookware for the skillet in the directions above. After  sautéing, place cookware in base, cover and cook as directed in recipe.
  • When blending hot liquids, remove the filler-cap in a two-piece lid and close any lid openings along the edge intended for pouring. Do not fill the blender more than half full. Hot liquids may push off the lid during blending. With the protection of an oven mitt or thick towel, place one hand on top of the lid, keep exposed skin away from the lid, and start blending at the lowest speed.
