I'm making a sour cream pound cake for an event. I would ideally like to make the batter in the morning. I have something else I have to do around 11:30, though, and I won't be home for about an hour.  Would it be ok to mix the batter together around 11, cover it, leave and come back? Would my cake be messed up in any way? Should the batter be refrigerated if I let it sit? 
Bury it in bread. A meat-substitute burger or kebab meat that has obvious textural or flavor flaws when served bare will often appear near perfect in a pita or bun. Also, you can keep a lot of oil/sauce on it that way, which carries seasonings and juicyness.  Start with baked seitan, made from vital wheat gluten (and 10-20% of another protein flour like lentil or chickpea optimally), and season both in the dough and when sauteing the cut up seitan later - experiment with which seasoning is best added at which time.  Try strong soy sauces (eg chinese light), cumin, smoked salt and/or smoked paprika, sugar, nutritional yeast/msg, flavorful chile pepper powders (eg turkish chile flakes - not just cayenne pepper powder!), garlic, onion. Also add something acidic, eg sumach or lemon.
