Place cheese and cornstarch in a sealable bag and toss to coat. Combine chicken stock, garlic and lemon juice in a fondue pot over medium-low heat. (If you don't have a fondue pot, you can prepare it ahead of time on the stove, using a small heavy-bottomed pot.
For the party, set the pot on a rack over a few tea lights to keep warm.) When stock begins to bubble, reduce heat to low and begin adding cheese a handful at a time, whisking gently until melted and fully combined. You may need to increase the heat to get all the cheese melted, but don't bring to a boil. Keep warm over low heat until ready to serve. Offer a variety of dippers to make a full meal.
