No doubt legions of fans who have travelled to Sao Paulo from all over the world will be snacking on the delicious street food for which the South Americans are famous as they follow the action on the pitch.
Some 6000 miles away, however, diners at a remote Hebridean restaurant will be enjoying a different class of Brazilian fare - courtesy of Marcello Tully, head chef of Kinloch Lodge on Skye and the only Brazilian-born chef in the UK to have a Michelin star.
To mark the first night of the tournament, Mr Tully has prepared a selection of special dishes that demonstrate his deep connection with the host country while using local Scottish produce.
Canapes will include Acaraje, a deep-fried treat of crushed black bean batter stuffed with Scottish langoustines; Coxinha, shredded chicken fried in bean batter and moulded into the shape of a chicken thigh; and Pao de Queijo, cheese choux balls.
Among the mains are the Brazilian national dish Fiojoada, stew containing pork trimmings such as pigs' ears, tongue and trotters; a Moqueca langoustine stew; and monkfish with lime and coconut sauce. Sweets include Brigadieros da Escocia or Highland Chocolate Brigadiers, little celebratory bonbons finished with local whisky Talisker.
Mr Tully, 45, said: "Scotland may not be in the World Cup but it has the best produce in the world. I hope Brazil get to the Final because it means I'll be making these wonderful dishes for my customers all the way through to mid-July."
The only other Michelin-starred Brazilian chef in the world is Henrique Leis, whose eponymous restaurant in Almancil, Portugal has held a star since 2010.00.
