@christlet Have you tried Massimo Bottura's variant?
@christlet I dont do the mint, the detail that worked for me to maintain a nice aspect was the ice. But the Big New Thing was using breadcrumbs in lieu of pine nuts. Which a) really does taste great & b) drives the cost to zero (pine nut prices are insane here in Portugal)
