Well, the title covers it.
I nonchalantly suggested that I could make a potato salad for a BBQ this weekend, and now, apparently, the host is "really looking forward to it". Bugger. I feel so much pressure. I haven't made one in years, and will probably need to make it the day before the BBQ and refrigerate (no time) and then haul it across London on public transport.
Anyone got an AMAZING recipe?
