March 1st is National Sunkist Citrus Day, and we spent it charring lemons and oranges.
Why?
To accent various foods and drinks, of course. But there’s a bonus benefit: Charring citrus fills the house with fragrance.
It’s far better than aroma of baking cookies for fragrance, a trick recommended by realtors when potential buyers come to view your home.
Be it lemon, lime, grapefruit, or orange, there’s plenty you can do with charred citrus.

WHY CHAR CITRUS FRUITS?
Charring any citrus fruit gives it more depth and complexity: the sweet notes are sweeter, the acidity is somehow brighter, and then the smoky aroma and flavor is a treat for lovers of smoky foods. See more of them below.
Charred lemons, limes, oranges, and other citrus fruits develop a smoky, caramelized flavor that adds depth and brightness to both savory and sweet dishes. There are numerous uses for them below.
Charred Vs. Grilled Citrus
In culinary terms, grilling is a controlled enhancement to a food, while charring is a deliberate transformation of it.
A grilled lemon is still fundamentally a lemon; a but a charred lemon is something more intense.
Grilled citrus is placed cut side down on a moderately hot grill, long enough to caramelize the surface sugars and warm the juice.
The heat mellows the sharpness of the acid and brings out a slightly sweeter, more rounded citrus flavor. The juice flows more freely when squeezed.
It’s a refinement of the fresh fruit: still recognizably bright and citrusy, but softer and more complex.
Charred citrus takes the flavor a step further, by exposing it to intense direct heat until the surface is blackened.
The sugars don’t just caramelize—they partially combust, introducing a distinctly smoky element with a tinge of bitterness.
The flavor is more aggressive and complex than the grilled version.
RECIPE: CHARRED LEMONS, LIMES, & ORANGES
Ingredients
12 lemons or limes, or other citrus fruits (as they’re larger, you’ll require fewer grapefruits and oranges)
Preparation
1. PREHEAT the broiler. Slice the ends off the citrus fruits, and then slice them in half.
2. PLACE the citrus on a cast iron griddle or a baking sheet with the cut side up. Broil on the very top rack, or as close as you can get, for 10 to 15 minutes or until charred.
3. COOL the citrus before using.

USES FOR CHARRED LEMONS, LIMES, & ORANGES
Charred lemons in particular have been having a moment in restaurant kitchens over the past several years, showing up in everything from cocktails to vinaigrettes to finishing sauces. The technique is simple enough for home cooks but adds a sophisticated touch.
All charred citrus fruits develop a smoky, caramelized flavor that adds depth and brightness to both savory and sweet dishes. Here are some popular and creative uses for them:
Breakfast: Mix into oatmeal or yogurt. Top avocado toast with bits of charred grapefruit and chili flakes.
Cocktails: Use the juice or slices of the fruit in drinks. We especially like charred lime Margaritas, smoky lemonade, and smoky Bourbon sours. Use charred grapefruit in Palomas and Whiskey Sours, and charred oranges in Old Fashioneds. Muddle lime wedges in a Gin & Tonic.
Compound Butter: Mix the zest and juice into softened butter with herbs. Use on grilled corn, steak, or as a bread/toast spread.
Desserts: Drizzle charred orange juice over pound cake or ice cream. Use charred grapefruit zest in baked goods or custards. Add to ice cream with a drizzle of honey or balsamic glaze. Use the juice in curds, sorbets, or even to flavor buttercream.
Garnish: Thinly slice and garnish cocktails, charcuterie boards, or roasted meats.
Glazes & Marinades: Mix with soy sauce, honey, or vinegar for grilled proteins or tofu.
Grilled Meats & Seafood: As a finishing element, squeeze over grilled chicken, fish, lamb, or shrimp.
Mocktails & Soft Drinks: Add the juice to sparkling water or soda. Add a touch of honey or rosemary syrup for a smoky spritz. Add some char to cola and lemon-lime sodas
Roasted Vegetables: Toss thin charred citrus slices with roasted broccoli, Brussels sprouts, or carrots.
Salad Dressing: Add the charred juice to vinaigrettes for a smoky, complex acidity; replace all or half of the vinegar with the charred juice, and add optional minced shallot. For a sweet variation, add Dijon, honey, and herbs. Add to homemade mayonnaise/aïoli. Both the vinaigrette aïoli works beautifully on grilled fish or vegetables.
Salads: Use thin slices in citrus-forward salads with avocado, or beets, or fennel. Add charred grapefruit to salads with arugula, avocado, and goat cheese/pistachios.
Salsa: Mix chopped charred grapefruit or lime with cilantro, jalapeño, and red onion to pair with grilled chicken or fish.
While not a citrus fruit, we want to give a shout out to charred tomatoes. Use them in:
Breakfast: Serve with eggs, shakshuka, or as a side to grits or hash. Chop and stir into Greek yogurt.
Bruschetta & Toast: Spread charred tomato onto crusty bread with olive oil and garlic.
Pasta & Grain Bowls: Mix into farro, rice, or pasta with fresh herbs. Top with burrata or feta cheese.
Salsas & Sauces: Blend into smoky tomato salsas, romesco, or arrabbiata sauce.
Soups & Stews: Add depth to tomato soups, chili, or gumbo bases.
MORE SMOKY FOODS
If you like smoky flavors, there’s world of smoked foods in the U.S. that goes way beyond the usual brisket, ribs, smoked salmon, and Lapsang Souchong tea. Here are more smoked foods to buy or make:
Smoked cheeses: it’s easy to find smoked Cheddar, smoked Gouda, and smoked mozzarella. Use them for grilled cheese, mac and cheese, and cheese boards.
Smoked eggs: hard-boiled then cold-smoked, these make delicious deviled eggs, egg salad, or on ramen.
Smoked vegetables: If you have a smoker, add veggies! Smoked broccoli, Brussels sprouts, carrots, corn on the cob, and sweet potatoes are delish.
Smoked seasonings: smoked paprika and smoked salt are familiar, but have you checked out smoked black pepper? You can also find smoked cumin, smoked curry powder, smoked garlic powder, and smoked onion powder; and chipotle seasoning is already smoked (chipotle is a smoked jalapeno). Liquid smoke can be quite handy. Each of these adds smoky flavors without needing to smoke the food.
