Amazingly, Nigella doesn't give any kind of Nigella-esque quote for this recipe. Don't know why, because it is a very Nigella-esque recipe! - Rose Red
The verdict: You know, when I first saw this recipe I thought "oh, shortbread dipped in chocolate. Whoopee". Clearly I didn't read past the first sentence, because this recipe is actually what we in Australia usually call Chocolate Caramel Slice - much more descriptive of what it actually is. Although the idea of calling it Millionaire's shortbread is very apt - it is as rich as all get out! Unusual or substituted ingredients: Nothing unusual. Just sweet sweet sweet - condensed milk, golden syrup, chocolate. Plus flour, butter and sugar for the shortbread. And because milk chocolate could not be decadent enough, I used dark chocolate. But of course!
Special utensils or cookware: Nigella says this recipe introduced her to the concept of both melting chocolate in the microwave, and also making caramel in the microwave. Having never made caramel at all before, I can't comment on the relative benefits, but it was very quick and easy to use the microwave. Nigella cautions to regularly check and stir the caramel to avoid burning it, and I followed this advice to the letter. In fact, I quite possibly didn't cook the caramel enough (about 5 or 6 minutes I think), but it still worked out absolutely fine! Amazing actually, watching the condensed milk caramelise.
Repeatability: Oh, I would definitely make this again. For sure! It is darn hard to cut though. The chocolate on the top cracked and so it ended up being a bit messy. Perhaps if the chocolate was a bit thinner it would be easier. Also, I recommend cutting into small pieces - it really is very rich.
Sauciness: Oh yeah baby! Plenty of bowls to lick with this recipe! As well as the tin of condensed milk (am I the only one who can confess to eating condensed milk straight from the tin? Sometimes my mum would have a tin in the fridge with leftovers, and my brother and I would compete to eat it in secret, a teaspoonful at a time...heaven!)
Overall pleasure level: I know some people find this too rich (husby wouldn't even try a tiny piece) but for me, it was divine! 10 out of 10. Make it - you won't regret it! (and lest you think I ate it all by myself, I took most of it into work!)
