Answer: Daaaaa, no! If you are going to heat your seeds as I recommend and as my protocol requires, you must do this prior to grinding. I suggest you heat a small amount at a time. Why? Incase you make a mistake. Many first time people heating seeds, mess up and burn them or undercook them.
If you have a small electric oven, I have found the nearly perfect way to heat seeds. Place 500 grams on a baking tray. Place them in a cold oven and turn the oven to 180 C. Turn only the bottom burner on and bake them for 14 minutes. Do not open the door when the bell rings that they are done. Let the heat steam them for at least 1 hour.
After 1 hour, open the oven door and taste the seeds to see if they are bland. They should not be harsh to the tongue but just ever so slightly tangy, more on the bland side.
