This bright, creamy herb sauce is the kind of thing you'll want to drizzle over everything — grilled fish, roasted vegetables, poached chicken, or even a simple grain bowl. The combination of fresh dill, briny capers, and lemon zest gives it a punchy, restaurant-worthy flavor that comes together in just a few minutes of whisking. One of the trickiest parts of managing a sensitive gut is finding sauces and condiments that don't sneak in onion or garlic — but here, garlic-infused olive oil delivers all that savory depth without the problematic compounds, making it a genuinely smart swap. Sour cream forms the creamy base, and because it's used in a modest, sauce-appropriate amount per serving, it fits comfortably within what's considered well-tolerated. Fresh chives add a mild onion-like note that works beautifully without the digestive baggage of the real thing. The whole recipe takes barely five minutes to pull together and keeps in the fridge for up to three days, so you can make a batch ahead and have a flavorful, gut-friendly sauce ready whenever you need it. It's the kind of recipe that quietly solves a real problem while tasting like it was made by someone who really knows their way around a kitchen.
