Walnut Grades Explained: In-Shell or Ready-Shelled Halves?
Walnuts sold at Mega Food Plus come in two very different forms: whole nuts still in their shell, and ready-shelled halves. Both come from the same tree, but they suit different kitchens, budgets and uses. Here's what actually separates the two grades, so you can pick the right one.
In-Shell Walnuts: What You're Buying
Our Whole Walnuts in Shell are sold exactly as they come off the tree — light, unbroken shells with the kernel protected inside. Buying in-shell means you're paying for the whole nut, shell included, so the price per kilo looks lower but the edible yield per kilo is smaller once you've cracked and discarded the shells.
In-shell walnuts also tend to keep well for longer, because the shell acts as a natural barrier against light, air and moisture — the main things that turn nut oils rancid over time. If you're stocking up for the run-up to Christmas, when whole nuts in their shells are a traditional table centrepiece and stocking filler, buying in-shell makes sense: they look the part and store well until you need them.
The trade-off is effort. Cracking walnuts by hand takes a nutcracker and a bit of patience, and the kernels don't always come out in neat halves — you'll get a mix of halves, broken pieces and the occasional stubborn shell fragment to pick out.
Ready-Shelled Halves: The Convenient Choice
Our Walnut Kernels – Halves arrive already shelled, cleaned and sorted, ready to use straight from the bag. For baking, salads or snacking, this is the grade most home cooks and small food businesses reach for, simply because there's no prep time and no shell waste to deal with.
Because you're only paying for the edible kernel, the price per kilo is higher than in-shell walnuts, but the usable yield is effectively 100%: every gram in the bag is nut you can eat or cook with. That makes the true cost comparison closer than the sticker price suggests, especially once you factor in the time spent cracking shells by hand.
Shelled halves are more exposed to air once the bag is open, so they benefit from being kept in a sealed, airtight container away from heat and light, ideally in the fridge if you're not getting through a bag quickly.
Which Grade Suits Your Kitchen?
If you're baking banana bread, dressing a salad, or need walnuts by the handful for granola or a cake topping, halves save time and give you a consistent, ready-to-use ingredient. If you want a natural-looking bowl for the table, a longer shelf life without special storage, or you simply enjoy the ritual of cracking your own, in-shell is the better buy.
Cafés and bakeries working to a production schedule almost always default to shelled halves or pieces, since kitchen time spent shelling nuts by hand rarely pencils out against the extra cost per kilo. For occasional home baking or gifting, either grade works fine — it comes down to how much time you want to spend on prep versus how much you're willing to pay per usable kilo.
A Note on Storage
Whichever grade you choose, walnut kernels naturally contain unsaturated fats, which is why both in-shell and shelled walnuts are best kept cool, dry and out of direct sunlight. Shelled halves last longest in an airtight container in the fridge or freezer; in-shell walnuts can be kept in a cool, dark cupboard or pantry for longer without special measures, thanks to the natural protection the shell provides.
