Kilner Mash and Store Set 2023 Bluebonnet Season Review Jason Merlo Photography. The Kilner Mash & Store Set can be used to create fresh, homemade guacamole and other foods such as hummus, baba ganoush and baby food, which can then be consumed or stored in the jar. The glass push top lid has a silicone seal to keep the contents fresh. Simply place the mashing basket on top of the jar and fill with the chosen recipe, then press downwards with the mashing tool to create the desired consistency. The glass base jar has a capacity of 17 US fl oz liter and is suitable for use in the dishwasher. We advise that all other parts are hand washed in warm soapy water.
