What is the best way to test FO/EO in hot process soap. I am basically trying to test the smell, strength, how long it lasts, etc. Is it best to make a 2 pound batch and scoop out 4 ounces of soap and add the appropriate grams of FO for 4 oz? Or is it better to do 1 pound batches of HP? I have about 10 FO i want to test.
