Prepare canned chickpeas for hummus. Drain and rinse the chickpeas from the can in cold water. If desired, pull off thin white skin on as many beans as possible. The hummus will be creamier without white skins from chickpeas.: The bowl of rinsed chickpeas should look clean and smell neutral, free of the metallic can scent. Rinsing under cold water removes excess brine, and if you have time removing some of the white skins yields a silkier mouthfeel. You'll notice a creamier result when the skins are removed, because there are fewer fibrous bits. A common mistake is skipping the rinse, which can leave a tinny flavor in the final hummus.
Roast garlic for hummus. (This step of roasting garlic for hummus isn’t required but in my opinion, tastes better than using raw garlic which can be bitter.) Heat a small skillet on the stove to medium heat. Slowly add garlic and olive oil and stir regularly for about 3 minutes while garlic roasts in the pan. Remove from the heat and transfer to a small bowl before garlic starts to brown. Garlic will be translucent and fragrant. Reserve the garlic oil pan for the next step.: As the garlic sweats gently in the pan with olive oil , the kitchen will fill with a warm, mellow scent that is far less sharp than raw cloves. Stop cooking just before any browning appears, the cloves should be translucent and fragrant, not bitter. This approach softens the garlic's bite and integrates more smoothly into the hummus. Avoid letting the garlic brown, as burnt garlic will lend an acrid taste to the spread.
Toast walnuts. To the same pan the garlic roasted in, add the walnuts. Turn heat to medium and stir walnuts regularly as they toast for about 2 minutes, before they burn. Turn off heat and set aside.: When the walnuts hit the same skillet, the first audible change is a soft crackle and the aroma becomes nutty and toasty within moments. Stir frequently so they toast evenly and do not develop bitter burnt spots. Toasting enhances their flavor and helps them break down more easily during blending. The usual error here is leaving them unattended, which can quickly lead to an unpleasant char.
Blend chickpeas. Set aside 1 tbsp of fresh chickpeas to garnish the hummus platter with later. Add drained chickpeas and garlic olive oil to bowl of a food processor and process for 2 minutes, pausing every 30 seconds to scrape down the hummus from the side of the food processor.: As you pulse the rinsed chickpeas with the reserved garlic oil in the food processor, you should see a coarse paste gradually forming, with a faint nutty scent from the canned beans and the garlic oil. Pausing to scrape down the sides ensures everything processes evenly and prevents dry pockets. This step lays the groundwork for a creamy texture, so don’t rush it; a common oversight is under-processing, which leaves the hummus grainy.
Blend all basil hummus ingredients. Add walnuts, tahini and lemon juice and zest then process for 30 seconds, scraping down the hummus, then process for another 30 seconds. Add to the food processor: basil leaves, water, salt and pepper. Blend 1-2 minutes more, scraping down the hummus from the sides every 30 seconds, until smooth. Taste test and check the consistency. If basil hummus is too thick, add 1/2 tbsp more water at a time and process again until it’s your desired consistency.: Adding the toasted walnuts , tahini , and lemon juice and zest will make the mixture smell bright and slightly nutty. When you include the basil leaves , a green, herbal perfume will rise from the processor. Process in bursts and scrape often, watching for a glossy, pipeable consistency. If it seems stiff, add water a half tablespoon at a time until it loosens. Over-thinning is the typical mistake, which makes the hummus runny rather than spreadable.
Plate and garnish hummus. Transfer to a large serving bowl and use a spoon to carve wells into hummus. Drizzle with olive oil, sprinkle with extra chickpeas and sesame seeds, and top with lemon wedges and basil leaves.: Spoon the hummus into a shallow bowl and use the back of a spoon to create wells, which catch olive oil and make the platter look abundant. When you sprinkle reserved whole chickpeas and sesame seeds , and place lemon wedges and a basil leaves sprig, the platter becomes visually inviting. A drizzle of extra olive oil enhances mouthfeel. One mistake is over-garnishing, which can distract from the hummus’s texture and flavor.
Set a burner on the stove to medium or medium high heat. If using a large double grill pan, turn on two burners. Add grill pan or cast iron skillet or frying pan to burner(s).: The pan should shimmer slightly when it's hot enough, but not smoke. Using the right temperature ensures the bread crisps quickly without burning. If the pan is too cool the bread will dry rather than brown, and if too hot the crust will char before the interior warms through.
Either brush the olive oil directly on the pan, then add toasts, or brush bread with olive oil on both sides then add toasts to the pan. Mix together garlic powder and salt and sprinkle on top of olive-oil coated toasts.: Whether you brush the olive oil directly on the pan or on the bread , the surface should look glossy but not greasy. Sprinkle the garlic powder and salt evenly so each toast has balanced seasoning. This step adds flavor pockets that complement the hummus. Avoid soaking the bread in oil, which makes it limp instead of crisp.
Every 1-2 minutes, flip toasts until they turn golden brown on both sides. Some will be done faster than others, so move them to a cooling plate. Continue flipping toasts until done grilling.: As the toasts sizzle, the edges will darken and the aroma of cooked bread will emerge, signaling readiness. Turn the slices every minute or two to achieve even color, and move finished pieces to a cooling plate so they stay crisp. A frequent misstep is leaving pieces in the pan too long, which can cause uneven charring.
Add the bowl of hummus to the center of a large serving platter. Add celery and carrot sticks and finish plating with grilled bread. Serve with a large spoon and enjoy.: Place the bowl of hummus at the center of a large platter, arrange the grilled bread , and tuck in the celery sticks and carrot sticks around the edges. The final platter should feel abundant and textured. Serve with a large spoon so guests can scoop and build bites. A common error is overcrowding the platter, which makes it hard to reach components comfortably.
