They turned out to look like a hamburger and two sausage patties and look like they would be hard, but they are not - they are soft but help exfoliate dull skin.
Grate the soap
Grind the oatmeal with the food processor until most of the full flakes are ground, but not into a fine powder.
Put the grated soap in the microwave safe bowl and add the 4-5 TBSP of water and microwave for 2-3 minutes.
Remove the soap from the microwave and stir up.
Add the oatmeal to the soap and mix until blended.
Spoon the mixture into lids and/or tubs and allow to harden. Remove by running a knife around the edge and gently lift out the soaps.
