Combine the egg yolks and sugar in the bowl of a heavy-duty mixer. Beat with the whisk attachment on medium speed until the mixture is thick and very pale in color and forms a ribbon when the whisk is lifted, about 5 minutes. With the mixer running, drizzle in the olive oil; beat for 2 more minutes. Add the milk and cream and continue to beat until all the ingredients are combined. Freeze the mixture in a gelato machine according to the manufacturer's instructions.

*RAW EGG WARNING
Food Network Kitchens suggest caution in consuming raw and lightly-cooked eggs due to the slight risk of Salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly-refrigerated, clean, grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell.
