Is there a 24oz~ Tupperware-type container that weighs 35grams or less?

From reading other entries here at BPL, I've started hiking with a Glad brand 3.5 cup (30 oz) plastic container with screw-on lid. It weighs 2.75 oz (78 grams) so it misses your weight target, but its a great sized bowl with a secure fitting lid. It sounds like you are going stove less but when not, it fits my Toaks 550 ml pot and lid, a titanium wind break, Venom alcohol stove, sponge, food scraper, matches, and alcohol measuring cap. A pretty cool set that's very tiny. I love the ideas that I get from this site.

I just weighed an empty Talenti frozen yogurt screw-top container at 45 grams; closer to your goal but probably not as long-lasting as the Glad or Ziploc.

I have a sub 6lb base weight for most of my hikes and love an empty peanut butter jar. It's under 2oz for a 28oz jar. It's super durable and the lid secures really well for cold soaking. Mine lasted my whole pct thru, and looks no worse for wear.

My 32oz mayonnaise jar is 52g, so the smaller ones should be pretty close. This one is Kraft brand with a fairly thick lid. My guess is the house brands are lighter.

Richard and Dale, do you happen to know what the brands of those products were? I'm pretty silly for not considering a food product when thinking of my options. You guys all opened up my perspective by a lot.

Mine was a jif crunchy peanut butter jar.

Have you considered just a ziploc-style bag? Even the largest gallon freezer bag weighs about 12g. Seal it to rehydrate, when ready to eat set the bag into your Heinie can and fold the top of the bag over the top edge of the can so you have the same shape and structure to eat of. When finished pull out the bag and re-seal, no clean-up needed.

Careful with Jif jars in winter – the lids get very brittle around 20d F.
