Cambodia's foundational aromatic paste: lemongrass, galangal, kaffir lime, turmeric, and shallots pounded into the flavor base of Khmer cuisine.
Kroeung is to Cambodian cooking what mole paste is to Mexican or garam masala is to Indian cuisine β the foundational aromatic preparation that defines the flavor identity of a cuisine. Unlike Thai curry pastes which lean spicy and shrimpy, kroeung is predominantly aromatic and fragrant, built on lemongrass, galangal, fresh turmeric, kaffir lime leaf and rind, shallots, and garlic. Different versions exist for different applications: yellow kroeung (for amok and mild dishes), green kroeung (using fresh herbs and green chilies, for grilled meats), and red kroeung (with dried chilies, for richer braises). The traditional method is the stone mortar β pounding the fibrous aromatics for 20-30 minutes into a smooth, almost elastic paste. Modern cooks use blenders, but many argue the stone-ground version releases more oil from the lemongrass cells, resulting in a more fragrant paste. Kroeung can be made in large batches and frozen in portion-sized amounts.
Serves 8
Slice all fibrous ingredients (lemongrass, galangal, turmeric) very thinly β this reduces blending or pounding time significantly.
Add ingredients to a stone mortar in order from hardest to softest: lemongrass first, then galangal, then turmeric, then shallots, garlic, and kaffir lime. Pound each ingredient until broken down before adding the next. Work for 20-30 minutes until a very smooth, fibrous-free paste forms.
Patience is the key to a stone mortar β rushing produces a paste with fibrous lemongrass strands that ruin amok's texture.
Add all ingredients and oil to a high-powered blender. Blend 3-4 minutes, stopping to scrape down sides, until as smooth as possible. The paste will be slightly less refined than the mortar version.
The finished kroeung should smell intensely fragrant β citrusy from kaffir lime, earthy from galangal, bright from lemongrass. If the paste smells raw, it needs more pounding.
Use immediately in amok, samlor korko, or any Cambodian curry, or portion into ice cube trays and freeze.
The slice-first technique is non-negotiable for efficient pounding β whole aromatics will never break down smoothly.
Freeze kroeung in ice cube trays, then transfer to bags β each cube is roughly 1 tablespoon, perfect for single-recipe use.
For the smoothest blender paste, soak the sliced lemongrass in water 20 minutes before blending to soften the fibers.
Green kroeung: use fresh green chilies and increase fresh herbs (lemon basil, mint) for grilled meat applications.
Red kroeung: use 4-6 soaked dried chilies for a richer, darker paste used in braised dishes.
Prahok kroeung: add 1 tablespoon prahok to the paste for the foundation used in samlor korko.
Refrigerate in a sealed jar up to 1 week. Freeze in ice cube trays up to 3 months. Cover the surface with a thin layer of oil to prevent oxidation in the refrigerator.
Kroeung is documented in Khmer culinary manuscripts from the Angkor period and is referenced in descriptions of royal court cooking from the 12th century. The three-variety system (yellow, green, red) reflects a sophisticated culinary taxonomy developed over centuries, with each type calibrated to different proteins and cooking methods. Kroeung-making remains a core skill taught in Cambodian cooking schools and households alike.
Kroeung is gentler and more citrus-forward, with less chili heat and more aromatic complexity from kaffir lime. Thai pastes typically have more shrimp paste and dried chilies. Kroeung is about fragrance first; Thai pastes about heat-and-salt balance.
Yes β Cambodian and some Southeast Asian grocery stores carry premade kroeung. Quality varies significantly; homemade paste made with fresh ingredients is measurably more aromatic.
Kaffir lime leaves are what makes kroeung distinctively Khmer. Lime zest plus a tiny amount of lime juice in the paste is a partial substitute, but the citrus character will be simpler.
