Used half quantity nuts (cashews), sesame seeds but same quantity spices except fennel seeds where I used 0.5 teaspoon. 1 teaspoon peppercorns & salt. Toasted all spices. Omitted tumeric. Pestle & mortar to roughly crush spices.
Buns were light and fluffy even though I used a proportion of spelt & wholemeal strong flours with plain flour. Would have liked more custard filling & may try again with double the amount of custard.
