Note (10/5/2012) : The latest version has a blue plastic lid instead of the original slotted aluminum lid. The new design is intended to hold the sticks better, vertically, and indeed people do seem to say that it works as intended. My review is for the original model w/ the aluminum lid, but almost everything still applies.] I love this popsicle maker - it's very well made and easy to use - especially for the price (which seems to vary (sometimes by the hour !) between $11.xx in the Winter to $18.xx in the Summer - I paid $13.xx Winter-2011). And I like the classic popsicle shape it makes and that it uses standard pops sticks. If you use a pops maker with custom sticks/holders, remember that you're going to have to collect them back from everyone later on. I think I've used it 40-50 times by now, and it still looks like new. But some of the low star reviews I've read, it's like they're talking about another product. I haven't had any problems with sharp edges, slots being the wrong size, removing the pops, or cleaning it. A few comments & tips - quite a few here, but all-in-all it's really pretty easy to use: 1. METAL EDGES (* * The new version has a plastic lid - reports are it seems to work ok) : I'm not sure how (a few) people are deciding that there are sharp metal edges. After reading about this I took the edge, and then the corner, and rubbed it up and down my cheek a couple of times - and nothing happened. I am a 6'-2" male, but I'm not made of leather either. You're definitely not going to get a good shave from it by any means. So maybe the manufacturing is better now - I don't know - but I never had a problem with anything sharp - not even close. In general the thing is very well made in my opinion. 2. FILLING : Fill the popsicle mold to about 1/4" from the top - you will see a ridge there where you should stop filling - that will allow room for the mix to expand as it freezes. 3. INSERTING THE STICKS : (This is where you will have a different experience with the new model w/ the plastic lid, so you can pretty much disregard this section) I have not had any trouble with sticks and the size of the slots, as some have remarked. Perhaps pops sticks are not entirely uniform in size ? Just make sure the sticks are dry - if they are wet they will swell and then you'll have problems. The problem some people are having is that there is nothing initially to hold the sticks from veering off vertical before the mix starts to solidify. Wood, being less dense than water tends to want to float up. And if the sticks don't stay vertical, it's hard to get the metal lid off. There are two ways to handle this : --3a : Fill the popsicle maker, start freezing it, then wait about 1 to 1-1/2 hours before inserting the sticks (although that depends a bit on your freezer's temp and how cold the mix is to begin with.) After that time, the mix will have solidified enough that it will hold the sticks vertical. --3b : For a bit of an engineered but slightly goofy solution, clip a 1-1/4" binder clip to the side stick so the little silver handles are horizontal. That way you won't have to remember to insert the sticks later. I found the smaller clips don't have enough weight - the sticks can still tilt off vertical. After the pops freeze, remove all the clips so they don't rust over time. I had photos, above, but there were recently removed as I guess they're not appropriately related to the new version. For any method, insert the sticks - not all the way - but so they stick up about 1-1/4" to 1-1/2". If you put them in all the way there isn't enough to hold on to later on, and when licking/eating them you'll be working around too much stick, so to speak. (Make sure you actually use the aluminum lid - if you don't, the exposed ends of the pops will dry out too much - my current theory anyway.) 4. STICKS For stick supply I just buy the box of 1000 craft sticks from Amazon - the size is right and they always work : Loew Cornell 1021254 Woodsies Craft Sticks, 1000-Piece I'm really not too worried about food grade sticks after backpacking all these years. If you're really concerned you can dunk them in a bleach solution for about one minute. (You know that's how they keep all that packaged lettuce from going bad ?) It depends on the strength of your bleach : you can use 3 TblSpns/gal for 2% bleach, all the way down to 1T/gal for 6%. The chlorine will just evaporate after it dries but it's pretty dilute anyway. (Btw, 1T = 3tsp) Let them dry out before placing in the mold. 5. REMOVING POPSICLES & STORING : Run individual popsicles in the mold under hot water for 10-20 seconds each. If you want to remove more simultaneously, soak for similar time in a vessel of hot water. (Some people have figured out how to remove the actual individual plastic receptacles, but I don't think it's really designed to do that.) Also I'm not too big on the idea of nonstick spray, which is an oil - and oil and popsicles doesn't sound appealing to me. Next, you can wrap them in waxed paper - it's cheap and there is no need to waste a non-biodegradable petroleum product like plastic wrap. Some people then store them in ziplocks; I use a tupperware type container. 6. CLEANING : I don't use the dishwasher - I have a 3/4" dia. bottle brush which works great for cleaning - quick & easy. 7. RECIPES : Remember, your sense of sweetness is much weaker for frozen things like popsicles. So your recipes will need to taste much sweeter at room temp for them to seem about right when frozen. 8. EMULSIFIER - Guar Gum : Almost all recipes will benefit from using an emulsifier (this is true for ice cream as well actually). An emulsifier ensures that the ice crystals formed will be smaller, thus the popsicles will have a MUCH smoother texture. Without one you will find most pops have a texture of compacted snow balls. I use Guar Gum powder which I get at a local health food store, but it's also available from Amazon. There are other emulsifiers like Xanthan gum and Arrowroot (or Agar-Agar but that costs a lot more). Guar & Xanthan are typically used for ice cream and popsicles. For anything besides Guar I'm not sure of how much to add, but it's prob. similar to Guar. For Guar use 1/2 to 1 tsp. per quart - if you use too much the pops will be gooey or slimy. Some recipes require the lower amt. - e.g. strawberry mixes. I'm tending to use the lesser amount now. It can be hard to mix in - so mix in slowly and use an egg beater or blender. And mix only for a bare minimum or you can get froth. One trick is to mix it in a small portion, then pour that into the larger portion. Pouring it through a strainer can remove some of the froth that can develop. And don't let it sit mixed in for hours or it really will get too gooey. I rarely make pops without it - it REALLY helps. **6/15/2012 - I just heard on NPR this afternoon . . . Guar is used big time in fracking . . . prices going up. Weird. You made it to the end - I do have a life and have to get back to it so . . . Good luck - it's fun !
