I'm glad I inspired you to make one!

And yep, only proper custard for me. Well, I didn't make it from scratch with a vanilla pod, cream and egg yolks, if that's what you meant? But I made it with Birds powdered custard and Canderel. 1 tablespoon of each plus half a pint of milk.
When I make it again I'm going to make a few adjustments.
I'm not sure if I would have missed the vanilla extract, lemon juice and zest, I can't say I noticed them. Might leave them out next time.
I'll try light brown sugar instead of muscovado, just for a lighter colour really, and I'll make it a bit more than 175g. I feel the sponge could have been a tad sweeter.
I'll add an extra tablespoon or two of the golden syrup. I felt that the syrup didn't soak sufficiently into the bottom part of the pudding, but that might have had something to do with the small circle of baking paper at the base of the bowl, perhaps it restricted the syrup soaking further through. So I'll leave that baking paper out.
I'll also cook it by microwave.
