In this "H" challenge, Chef Lauren Gulyas decides to take on the unique flavours of halibut and horseradish. She starts with a perfectly prepared prosciutto wrapped halibut, pairing the buttery flavour of the fish with the saltiness of the cured meat. Throw in some dill potatoes and you've got a beautifully balanced dish. Next up, Chef Lauren show us how to make a delightful roast beef dip with a zesty horseradish sauce using carrots, vinegar, mayo and a little lemon. Finally, she is challenged to make a dish that combines both ingredients, and does she ever deliver.
