There's nothing more delicious than your own groundnut butter or ground nuts to put in your breakfast bowl.
But can we grind nuts through our coffee grinder?
Nuts contain a high level of oil which when roasted or ground are released. When you put nuts through a coffee grinder they are crushed and heated due to friction, this will release the oils into the coffee grinder and create a gooey mess.
For chopping nuts, I suggest a simple blade coffee grinder. This will keep the grinder free of oils as you can wash out the chamber after each time.
A blade grinder will cause all sorts of problems so best to avoid them.
If you really want a nice nut butter then something like the Nutramilk would be perfect for your family.
