New Cake Lab: part one of many: NHL Saucepan Cake!

Who needs Nigella when we have our very own Ann? Her delicious New History Lab Saucepan Cake has been a great hit. I reckon the brazil nuts are the master stroke as walnuts can be rather bitter. This is the first in what I hope will be a rather long and delicious series, with further instalments including one from that other domestic goddess, Rob, and his delicious lemon cake. Thanks, Ann!
Ingredients
12 oz well crushed digestive biscuits
3 oz butter
3 tbs golden syrup
7 oz chocolate
1 orange
1.5 oz glace cherries
1.5 oz finely chopped nuts (I use brazils)
1.5 oz sultanas
Method
Melt chocolate, butter and golden syrup in a saucepan.
Add juice of half an orange.
Stir in all the rest.
Divide mixture between two Victoria sandwich tins lined with non stick paper.
Flatten down with the other half of the orange.
Chill for 1 hour.
Divide each into twelve sections (but keep in tin)
Chill until fully set.
Enjoy!!!
