Adjika (Abkhaz: аџьыка, аџьыкаҟaҧшь or aџьыкаҵәаҵәа, Georgian: აჯიკა, Russian: аджика; often rendered adzhika in English) is a hot, spicy but subtly flavoured paste often used to flavour food mainly in the Caucasian regions of Abkhazia and Samegrelo. Adjika is usually red, though green adjika can be made with unripe peppers. The name itself comes from the Abkhaz word аџьыка "salt" (the more descriptive аџьыкаҟaҧшь (literally, "red salt") and аџьыкаҵәаҵәа are also used to refer specifically to adjika).

The Abkhazian variant of adjika is based on a boiled preparation of hot red peppers, garlic, herbs and spices such as coriander, dill, blue fenugreek (only found in mountain regions such as the Alps or the Caucasus), salt and walnut. A dry form of adjika exists that is sometimes called svanuri marili in Georgian (სვანური მარილი "Svanetian salt"); this looks like small red clumps mixed with a looser version of the spice mixture^{[citation needed]}. Home-made adjika is available from many market stalls in the Caucasus and in the Krasnodar Krai of Russia. Tomatoes are not an ingredient of traditional adjika, though different versions of adjika, sometimes having tomatoes as a main ingredient, are produced on a commercial scale and sold in supermarkets in Ukraine and Russia.
