Rupjmaize is a traditional dark bread made from rye and is considered to be the staple of the Latvian diet.

[1][2] The first written references to Latvian rye bread are found in a recipes book dating back to 1901.

[citation needed] The bread is made in a wood fueled hearth furnace from coarse (1740. and 1800. type) rye flour, with the addition of malt and caraway seeds as ingredients, giving the bread its characteristic flavor and aroma.

[3] It is also used to make Rupjmaizes kārtojums, a traditional Latvian dessert.

Salinātā rudzu rupjmaize is a special type of Rupjmaize, which has been sweetened by pouring hot water over (part of) the rye flour.
