Perfect decadent summer dessert, but nothing to feel very guilty about because it is made with nonfat Greek yogurt.

Pouring the dairy and Nutella base into the machine requires an immediate start to churning to prevent fat separation. Emulsifying the thick Greek yogurt, milk, and half-and-half correctly relies on ensuring all liquids share a refrigerator temperature of 38 degrees Fahrenheit before mixing. Whisking vigorously eliminates lumps of hazelnut spread that would otherwise freeze into hard, unpleasant pellets during the process.
Incorporating nonfat Greek yogurt significantly reduces the fat content typically found in standard gelato bases. Skim milk and half-and-half provide the necessary balance of milk solids and butterfat to prevent icy crystal formation. Freezing temperatures below 0 degrees Fahrenheit in the machine canister allow water molecules to crystallize rapidly while the paddle continuously incorporates air for volume. Over-churning breaks down this delicate emulsion, resulting in a grainy texture.
