Oh. I’m VERY reliably informed that Nocello is Walnut and Hazelnut. Where as Nocino is the 100% Walnut. That’s what Toschi tell me anyway. Whether other Nocello’s are different I don’t know. But I promise you, this Nocello is deffo Hazelnut and Walnut.
In the UK, we've got LOADS of "non-alcoholic Spirits" these days, you can substitute with any of those...or just omit. But bearing in mind it'll change the flavour.
Stryyk, Lyres, Everleaf, Seedlip, Crossip…they’re the really big players. But then Gordon’s, Sipsmith, Bombay, Tanqueray, Haymans etc etc etc all do non-alcoholic Gins too. Plus then you’ve got Monin for example that do Rum flavoured Sugar.
