Precisely! It began life as a classic quick-night Mongolian beef but made with ground beef (a trick Asian families have been doing for years).
But I thickened it and reduced it and let it cook slow so the collagen in the beef broke down, turning it into much more like a chili, but with Mongolian beef spices and flavor profile.
THEN it was time to go crazy and add my version of a cream sauce, which started as a classic béchamel, but then I cooked lots of onions in it (turning it into a "sauce soubise") and then adding cream (turning it into a sauce suprème), then blending and straining.
That makes it creamy and rich and earthy, with LOTS of mushrooms--all added to give it a sort of Euro-Asian Fusion stroganoff quality.
Went great with the lightly stir-fried greens.
