This week I have mostly been eating caviar. I don't think I've ever had it before, so I got a (£4.99) jar of lumpfish caviar from Tesco for the hell of it at Christmas, and put some on the smoked salmon blinis we had as a starter for our notchristmas dinner. I liked it, but no-one else did, so I've been putting it on stuff since, typically breakfast eggs (poached/scrambled), but also crackers with cream cheese.
Now I just need an income to support this new habit!
(Not really, it's quite an affordable now-and-again treat - for certain values of affordable - but I'm guessing the 'good' stuff is more expensive).
