Tips
Slice potatoes evenly to 1/2-inch thickness so they cook uniformly and develop even char marks without drying out.
Prepare the dressing while potatoes cool to save time; flavors meld better when potatoes are still warm.
Toast the lime zest briefly in a dry pan before adding to dressing to intensify its citrus aroma.

Cover and refrigerate up to 3 days. Dressing may separate; stir before serving.
Grill and chop potatoes up to 1 day ahead. Make dressing same day. Combine no more than 4 hours before serving to avoid sogginess.

Common Mistakes
Slice potatoes unevenly to avoid undercooked or burnt edges.
Skip cooling potatoes to avoid wilting the herbs in warm dressing.
Grill on too-high heat to prevent burnt exteriors with raw interiors.
Substitutions
FAQ
Can I make this salad ahead of time?
Grill and chop potatoes up to one day ahead. Prepare the dressing on serving day. Toss together no more than 4 hours before serving to maintain texture and prevent the salad from becoming mushy.
What if I don't have Thai basil?
Fresh mint or cilantro works as a direct substitute at a 1:1 ratio. Both provide brightness and herbal notes, though cilantro will taste more peppery and mint more cooling. Adjust turmeric slightly if desired.
Can I freeze leftovers?
Not recommended. The yogurt and mayo-based dressing separates and the potato texture becomes grainy when thawed. Refrigerate leftovers in an airtight container for up to 3 days instead.
