things people ask

• Why does my gingerbread weigh so much more than the recipe suggests?
  Molasses is denser than most baking liquids. At 340 g per cup, a single cup pulls roughly 100 g more than a cup of water and far more than a cup of oil. If you scaled a gingerbread recipe by volume but the dough feels heavier than expected, the molasses is doing it. Weighing the cup keeps the flour-to-molasses ratio honest across batches.
• Can I substitute blackstrap for regular molasses cup-for-cup in shoofly pie?
  By volume, yes — both run about 340 g per cup. By flavor, no. Blackstrap is bittersweet and mineral-heavy, the third boil after most of the sugar has been extracted. A full cup in shoofly pie or gingerbread will dominate. Most bakers use light or dark molasses for sweets and reserve blackstrap for baked beans or savory glazes where its bitterness reads as depth.
• How do I get a sticky cup of molasses out cleanly?
  Lightly oil the cup first, or measure molasses in the same cup you just used for an oil or butter ingredient. The thin film breaks the surface tension and the molasses pours out in one slow ribbon instead of clinging in tablespoon-sized streaks. For full-batch BBQ sauce or baked beans where you're adding a cup at a time, this saves real grams of waste.
