I had some canola oil and corn oil and thought I'd do a 50/50 mix of the two oils.
Try it with some avocado oil when you get a chance! That's my new favorite. You can certainly get it quite reasonably priced, but I find the extra few bucks for La Tourangelle. I get it by subscription on Amazon, which drops the price almost to half of what I'd been paying in my local grocery store. Yeah, yeah, I mostly shop local, and I'll happily spend a little more to keep my money on the island...but double?
Anyway, the price is probably closer where you are, so you can shop locally with a clean conscience and without breaking the bank. But it really does make for tasty mayonnaise. It's got a buttery flavor that other oils don't, so I'm finding more and more places to use it in. Great stuff!
(And I've definitely been meaning to start an oil thread! I could live on really good olive oil, and sometimes have!)
