Gewürztraminer is like the grown-up version of Moscato. It's lower in acidity, has more punchy aromatics, and higher alcohol content. It's tell-tale sign is the lychee or sweet rose aroma that makes it identifiable in a blind tasting.
It's a pink grape & is well known for it's intense floral aromas, and a distinct lychee note. On the palate, quality wines will have notes of grapefruit, rose, ginger. Such aromatics will give it an inherently sweet flavor, even though it can be made in a dry style, similar to Muscat, Riesling, or Torrontes.
Think exotic Middle Eastern & Moroccan cuisines which use nuts & dried fruits for pairings. Hummus anybody? What's important is to match the wine's floral & ginger notes in the dish.
