Turn on SAUTE and press Adjust to raise temp to MORE. When display reads HOT, add coconut oil and butter. Wait about 1 minute then pour in corn kernels. Stir and make sure the fat is covering all the kernels. If not add more oil. Cover (I use the IP glass Iid) and in 2 minutes or so the corn will start popping. When about 2/3 of the corn has popped, turn IP off and let sit to finish popping. Add salt and any seasonings of choice.
