A new Yotam Ottolenghi cookbook is always an occasion to rejoice.

After all, the London restaurateur is a seven-time New York Times best-selling cookbook author.

His latest, “Ottolenghi Test Kitchen: Shelf Love” (Clarkson Potter) of which I received a review copy, was written by him and Noor Murad, head of the Ottolenghi Test Kitchen.

Unlike most of his other cookbooks, which showcased dishes from his acclaimed Nopi and Rovi restaurants, and Ottolenghi delis, this one aims to show you more creative ways to cook from your pantry, fridge and freezer.

That being said, that doesn’t necessarily mean these are recipes that take barely any time or effort to put together. If you know Ottolengthi recipes, you know they often require a number of steps. But in this case, none are especially difficult or laborious. And in many cases, you’ll learn a new tip or technique along the way. Many of the recipes also list handy substitutions or additional ways to use a particular sauce or serve a dish.

Case in point, “Creamy Dreamy Hummus,” which Murad and Ottolenghi provide directions for making with the preferred dried chickpeas, as well as with, yes, canned garbanzos, often considered sacrilege. But, as they note, canned ones can still create a very creamy hummus — provided you first use kitchen towels to gently release their skins, then cook them briefly in water with salt, and a pinch of cumin.

Or take the recipe for “Very Giant Giant Couscous Cake,” a clean-out-the-fridge type of crispy, savory cake made in a pan that can be put together with leftover rice or pearl barley, if you don’t have couscous on hand.

Or the “Skillet Berries, Bread, and Browned Butter” breakfast, brunch or afternoon snack that makes use of half-opened bags of frozen berries, stale bread, and that forgotten container of rolled outs by turning it all into a delicious warm fruit crumble drizzled with cold heavy cream.

With a butternut squash languishing on my countertop for a couple of weeks, I was moved to try my hand at “Butternut Squash with Orange Oil and Caramelized Honey.”
