DRY commercial formula.  Follow instructions on bag and mix accordingly	add  macadamia oil mix lightly	add  prepared mash.  Mix lightly. Add liquid if needed for consistency Note: glass cup and sterile tablespoons
Care to be given not to dip the spoon from the formula back to the mash.  I  count out my portion and drop into the commercial formula without the spoon touching. Once the mash is in the formula then I mix both completely.
