Queue recipe snapshots at your own batch sizes, combine their oil requirements and compare the result with stock on hand. HOW IT WORKS 1. Open Batches, then Workshop. Choose Plan a batch and a saved recipe. 2. Set oil grams per batch and the number of batches, then save the plan. 3. Tap an oil to record current stock. Share the combined oil pick list. 4. Mark a plan complete to remove its demand, or reopen it later. Keep the recipe calculator, fat library, saved recipes, costing tools and poured-batch journal. Workshop snapshots remain stable when a saved recipe is edited. WHAT TO KNOW Workshop covers oils only. Lye, water, fragrance and additives are excluded; calculate and verify each recipe before making soap. Stock is manual and is not deducted automatically. Cure milestones measure elapsed time and do not certify safety. iPhone and iPad.
