Now here's the recipe I was looking for - for some reason it didn't come up when I searched my blog, though I was sure it was there. I've had to trawl through all the entries tagged with recipes to find it - it would have probably been faster to find the magazine!
The recipe came from an old magazine: Better Houses and Gardens, a Christmas issue.
3 egg whites
1 cup caster sugar
3 1/2 ounces desiccated coconut
1/2 cup ground pecans
1/2 tsp vanilla
Beat the egg whites and vanilla to a soft peak. Add the sugar one tablespoon at a time, beating on high speed for at least 5 minutes or till very stiff. Fold in the nuts.
Drop teaspoons onto greaseproof paper, two inches apart, and cook for 18 - 20 minutes at 325F, 160C, till the edges are lightly browned.
This makes about 45.
