• Chocolate Fudge Cake

  I made Nigella's Chocolate Fudge Cake in Australia and it was moist and beautiful. However now I live in San Diego and when I made the cake it was completely different, it was dry and broke up. Any ideas?

• Chocolate Chips for Cookies

  I'm really struggling to find decent quality dark chocolate chips anywhere in London, can you recommend anywhere or should I give up? Will cutting up a bar of good chocolate and adding that do instead? I am worried about them just melting and making a mess rather than staying as chocolate morsels within the baked cookie.

• Frangelico Tiramisu

  I made Nigella's Frangelico Tiramisu last week for the first time. It tasted absolutely delicious but I wonder if I did something wrong. When I started to serve it after its 6 hour chilling, I found that there was quite a lot of the espresso mixture in the bottom of the dish; it was as if most of the liquid had sunk to the bottom during refrigeration. I followed the recipe and thought I was being careful to use exactly half of the Frangelico-espresso mixture in each of the two layers. But the tiramisu was so wet at the bottom, I felt it spoiled the dessert somewhat, even though it tasted lovely. What might have gone wrong and how can I resolve this next time?
