They have a lemon zest flavoured shell with a lemon curd filling. This is what they ideally look like:
Overall I was pretty pleased with my first go, especially as every recipe I've seen has emphasised that it's very unlikely you'll get them perfect first time! Mine were a little undercooked and the shell's definitely show my lack of piping skills. But they taste like they supposed too and I learnt lots, so I'm looking forward to next time!
If anyone else wants to give it a go I used PastryPal's excellent downloadable e-book (free) and Alison Thompson's book 'Macaron'
That's all for now,
