Nigella's chocolate salami - biscuit substitution?

[AgentProvocateur]

I fancy making the salami on tonight's programme, but I hate amaretti biscuits and amaretto liqueur. I would use brandy, but what biscuits would you use? Are digestives too boring, or are they just there for texture?

Digestive, hobnobs or ginger nut! It did look lovely :)

I make a similar version using rich tea biscuits, ginger nuts would work well I think, have tried it with digestives and they go a bit mushy for how I like to eat it but am sure it would work with any type of biscuit.

Ginger nuts, it is. Thank you.
