We all scream for ice cream.

On Thursday night, Argentina will be celebrating its seventh annual Noche de Las Heladarías (Night of the Ice Cream Parlors), with more than 400 locations offering discounts on select ice creams and confections.

The event is organized by Argentina’s Association of Artisanal Ice Cream Makers (AFADHYA, by its Spanish acronym), which calls it the “happiest night of the year.”

Some of the new ice creams on offer this year are dulcemate, which is derived from the popular Argentine drink, and bombón argentino, a peanut butter and chocolate concoction that will delight your palate, disturb your dentist, and disgust your dietician.

You can also enjoy inventive flavors like sambayón (based on an Italian dessert of sweet cream egg yolk and wine), chocotorta (chocolate cookies, mascarpone, and dulce de leche), quinotos al whisky (kumquats with whisky), and crema rusa (a creamy ice cream with chunks of walnut).

Many, if not all, of the Herald’s favorite ice cream shops will be open tonight. A few others worth visiting include Dolce in San Isidro, where you can get a 50% discount on delicious chocolates like Peruvian and Ecuadorian cacao; Martinelli in Colegiales, which boasts some of the best cannolis in Buenos Aires; and Sui Gele in Palermo, where you can sample an exquisite white chocolate ice cream topped with a blueberry sauce.

If you can’t make it to one of these spots, you can always visit your neighborhood Chungo, which is having a 2×1 sale on quarter-kilo containers (polystyrene tubs weighing about half a pound).

Prices at each location may vary. For a complete list of businesses participating in this year’s event, visit the AFADHYA website here.
