"She teaches very regional, very authentic, rural, rustic Italian cooking. She doesn't do anything else but cook."
Italia takes Mamma's recipes and makes them achievable meals that families of any means can make.
"So these recipes are my take on her recipes because while she can take a whole day preparing something, I'll chuck it in the food processor and it's done in two minutes, so I think that really appeals to New Zealanders.
"In Italy, it's about what you've got, what you grow. Italian cooking is born out of frugality and poverty, like learning how to feed a family on three tomatoes and a bit of bread."
With so many delicious recipes and beautiful photographs filling the pages of Italia, it's hard for Seagar to choose a favourite, but said a recipe for black pepper, lime juice and buttermilk gelato "jumped out" at her.
"I know it sounds strange, but it's like a mouthful of cold fire and ice and it was something I had never tasted before, which is thrilling for a foodie to experience.
"I was also able to make some kiwi dishes for Mamma, from flavours that she had never tasted before, like coriander, which is not Italian, coconut milk and sweet chilli sauce on raw fish."
