Chinese walnut cookies
Hap toh sou are a fixture of Cantonese bakeries in Guangzhou and Hong Kong, sold loose by the catty or packed in red tins for Lunar New Year visits, when walnuts stand for family happiness. They are wide, crumbly and slightly sandy, with a cracked golden top crowned by a walnut half and a gentle sweetness that suits a pot of oolong or pu'er. Traditionally they are made with lard, which gives an extra-short crumble; this version uses vegetable shortening or neutral oil, so it is vegetarian. The top is brushed with beaten egg for shine; milk mixed with a little honey or golden syrup is an egg-free alternative. A common mistake is pressing the balls flat: leave them domed and they crack open naturally in the heat. Chef's tip: toast the walnuts before chopping; it deepens their flavour and keeps them crunchy inside the soft crumb.
