I carry olive oil to supplement freeze dried foods. I've always stored this in small disposable bottles (from water, juice, whatever), most of which have sealed without incident.
I've had a much harder time finding wide mouth containers for oil or oily foods–for example, natural nut butters where the oil separates, or oil-packed sundried tomatoes. I bought one of those little 4oz capacity nalgene jars, and it leaks oil like crazy. Because I don't trust the jar, I've tried putting the jar in a ziploc, but dealing with the oily jar is messy.
Can anybody recommend a wide-mouth container that will hold at least half a cup, and that seals well enough that oil stays in even when hiking in 90 weather?
