Learn to use the Kilner Mash and Store Set for fresh guacamole, hummus, and baby food, then store leftovers in the jar.
Quick Answer
Use the Kilner Mash and Store Set to mash ingredients directly in the jar, then seal and refrigerate for later.
Why Mash Directly in the Jar
Mashing directly in the jar saves dishes and keeps your food fresh. The set is designed for small-batch preparation, so you can make just what you need.
The jar doubles as a storage container, so you can go from prep to fridge without transferring food. This is especially handy for baby food or single servings.
Know the Limits
The set works best for soft foods like avocados, cooked beans, or steamed vegetables. It is not meant for heavy-duty mashing of hard, raw ingredients.
For larger batches, use a traditional masher or food processor, then transfer to the jar for storage.
Step-by-Step Guide
- Prepare Your Ingredients: Cut soft ingredients like avocados, cooked beans, or steamed vegetables into chunks that fit comfortably in the jar. Avoid overfilling; leave room for mashing. Check that your ingredients are soft enough to mash easily.
- Mash to Your Preferred Texture: Use the masher to press and twist ingredients against the jar bottom. Work in short strokes, scraping the sides as needed for an even consistency. Stop when the texture looks right; over-mashing can make it too smooth.
- Season and Mix: Add seasonings, lemon juice, or other flavorings, then mash and stir to combine. Taste and adjust if needed. Mix thoroughly so flavors are evenly distributed.
- Seal and Store: Wipe the jar rim clean, place the lid on, and seal. Refrigerate promptly if not serving immediately. Always refrigerate leftovers within two hours.
- Clean Thoroughly: Wash the jar and masher in warm, soapy water after each use. The jar is dishwasher safe, but check the masher for any special care instructions. Dry completely before storing to prevent odors.
