I don’t like throwing out the olive oil that my tuna comes packed in but if I leave it in the tuna salad is a bit too runny. Today, I decided to drain the tuna and use the oil as part of the oil in a batch of mayo. I didn’t need all the mayo for the tuna salad, of course – it’ll be interesting to see whether I like the tuna-flavoured mayo in other applications.

If I have any mayo left a week after I’ve made it, I typically toss it into whatever creamy casserole I’m making at the time. I think the tuna mayo will work nicely for that, at least.
