No. Denningvleis, a traditional Cape Malay lamb curry, is typically flavoured with tamarind, which carries the same tartaric acid toxicity risk as grapes and raisins.
Tamarind contains tartaric acid, the same compound implicated in grape and raisin toxicity in dogs — our grapes page covers the full mechanism, and it applies directly here. This is one of the more surprising entries on this site precisely because denningvleis doesn't look anything like a grape dish, but the shared ingredient carries the shared risk. The dish is also typically onion-based on top of that.
