*If you can't source hazelnut meal, buy raw hazelnuts and make the meal yourself. Simply roast the nuts at 160 Celsius (320F) for 10-12 minutes, let cool, then process the nuts, skin and all, until it resembles a coarse meal (don't take it too far or it will become a nut butter).
**Light olive oil is flavourless - don't use Extra Virgin Olive Oil, as this is too strongly flavoured. As a substitute, use a flavourless vegetable oil instead.
