Pebre shows up at nearly every Chilean table before the meal, served in a small bowl with bread for dipping while the grill heats up. It's lighter and more tomato-forward than chimichurri, and the cilantro base makes it taste distinctly different from its Argentine cousin.
Chimichurri is oil-heavy, parsley-based, and works best on red meat. Pebre is lighter, tomato-forward, and works better on chicken, fish, and pork. Pebre is also the better choice as a bread dip or a sauce for empanadas. For grilled beef, chimichurri wins. For grilled salmon or white fish, pebre is the better call. Serve both at a mixed grill and let people choose.
In the south of Chile, pebre often includes merquén - a smoked, dried ají chile used like a spice blend, with coriander seeds and salt. A pinch of merquén added to the base recipe gives a smoky depth that works particularly well with lamb and beef. It's available at some specialty stores and easily ordered online.
Some versions skip tomato entirely and go closer to a pure herb salsa. Others add finely chopped cucumber for extra freshness in summer.
Pebre is best eaten within a few hours of making. The tomato releases liquid and the cilantro wilts after a day in the fridge. If you need to make ahead, keep the herb-oil-vinegar base separate from the tomato and onion and combine 30 minutes before serving.
Make it the day of. The 10-minute prep time doesn't justify batching it like chimichurri. Pre-mince the aromatics and refrigerate, then combine with the fresh tomato and cilantro when needed.
