Note the similarly named manjar blanco in Latin American cuisine.
Manjar branco is a pure white Brazilian coconut pudding similar to blancmange. It is identical to the Puerto Rican tembleque. In Brazil manjar branco is made in a ring mold and is served with a sauce made of pitted prunes poached in port wine. Commercial mixes for manjar branco and tembleque are available in Brazil, the U.S., and in other Latin American countries.
In order to improve the texture and taste, unsweetened shredded coconut may be added to the mix.
Manjar branco in Portugal usually refers to blancmange. In particular the manjar branco of Coimbra preserves the historical recipe for blancmange, and is made from chicken breast, milk, sugar, rice flour, orange zest, and salt.
