Step 1Preheat the oven to low, 100 °C/ 210 °F (fan assisted), or 120 °C/ 250 °F (conventional). Wash the kale thoroughly and make sure you drain it completely (paper towel works best). If you don't dry it enough, it will get soggy. Remove the stems and tear or chop into large-bite-sized pieces. Don't make them too small, they'll shrink a bit while baking.
