Learn how to use your Kilner Spice Jar Set to store and organize freshly ground spices. Step-by-step instructions for grinding, filling, and sealing glass jars.
Quick Answer
Use the Kilner Spice Jar Set to store freshly ground spices in the wooden crate, keeping them close at hand and protected from light.
Why Glass Jars Work Best for Ground Spices
Glass jars, like those in the Kilner Spice Jar Set, do not absorb odors or oils from spices, so your blends stay true to flavor. The clip-top seal locks out moisture and air, which are the main enemies of ground spice freshness.
Unlike plastic containers, glass is non-porous and easy to clean between uses. This makes it simple to switch from storing cumin one week to cinnamon the next without cross-contamination.
Choosing the Right Spices to Grind
Whole spices retain their essential oils much longer than pre-ground versions. For best results, grind only what you will use within a week or two. Common candidates include cumin seeds, coriander seeds, black peppercorns, and cardamom pods.
Avoid grinding very oily spices like nutmeg or cloves in large batches, as their oils can degrade quickly. Instead, grind them fresh each time and store any leftover in the Kilner jars for a few days.
Step-by-Step Guide
- Grind Your Spices Fresh: Use a spice grinder or mortar and pestle to grind whole spices into a fine or coarse powder, depending on your recipe. Grind only as much as you plan to use within a week. Don't over-grind; stop when you reach your desired texture to avoid overheating the spices.
- Fill the Kilner Glass Jars: Spoon the freshly ground spice into a clean, dry Kilner jar. Leave about 1/2 inch of headspace to allow for easy mixing and sealing. Avoid overfilling, which can prevent the clip top from sealing properly. Make sure the jar rim is free of spice dust before closing, or the seal may fail.
- Seal with the Clip Top: Press the glass lid down and secure the wire clip over the top. The rubber gasket should create an airtight seal. You should hear a slight pop when the seal engages. If the lid doesn't feel tight, check that the rubber gasket is seated evenly and the jar rim is clean.
- Store in the Wooden Crate: Place the sealed jars into the wooden crate, labeling each jar with the spice name and date. Keep the crate in a cool, dark cupboard away from direct sunlight and heat sources. Avoid storing the crate near the stove or oven, as heat can degrade spice oils quickly.
- Use Within Two Weeks for Best Flavor: Ground spices lose potency faster than whole ones. For optimal taste, use your freshly ground spices within two weeks. After that, refresh your supply with a new batch. If the spice aroma fades or becomes dull, it's time to grind a fresh batch.
