    Hi Guys! Okay, so I have sort of a random question for you and I’m really hoping someone out there has an answer for me…if you are a glasses wearer, how do you alleviate the fogging issue??? I’m serious. I finally got glasses last week, after realizing driving at night was beginning to get a little dangerous. So now I wear these things on my face, most of the time, and the fog issue is out of control!! If you know me personally, you know that I’m always hot or get hot very easily. I can be sitting in a room, doing absolutely nothing and I can feel my cheeks getting warm. Why? I have no idea! This was never a real problem until glasses happened to me. Now the second my cheeks get warm, major fog-age! Terrible! I know this is super nerdy, but I would really love any tips or advice anyone might have. I’ve read things online about rubbing Vaseline onto your lenses, but that just seems weird and gross to me…plus I’m worried about ruining the ‘fancy’ coating that are apparently on my lenses. So if anyone could help me out with this lil’ problem I would love you forever and ever and ever!

    Anyway, moving past my personal issues and onto today’s recipe. We have a Sweet Potato and Rosemary Gratin! This gratin is easy, very easy. I used buttermilk instead of the usual milk or cream because I like the slight tang it adds to this dish. Just one little thing… please don’t skip out on the broiling part at the end! The crispy crust that’s created, up against the soft, savory interior? HEAVEN! And because sweet potatoes and rosemary were pretty much made for one another I threw a little of that in there as well. If you’re looking to spice up your thanksgiving table, this quick and easy sweet potato and rosemary gratin might be worth trying out! Enjoy! xx, Jenny

    RECIPE BY Teri & Jenny
    Prep Time: 20 mins
    Cook Time: 35 mins
    Rest/Cool Time: 30 mins
    Servings: 8

      INGREDIENTS  

    • 2 sweet potatoes, sliced into ⅛” rounds
    • 1 cup buttermilk
    • 3 garlic cloves, minced and divided
    • 1 tablespoon minced rosemary
    • ⅔ cup freshly grated parmesan, plus more for topping
    • salt and pepper to taste

    garnish

    • ½ teaspoon minced rosemary

      INSTRUCTIONS  

    • Preheat oven to 375˚F. Line a round 8” cake pan with parchment paper and set aside.
    • Place sweet potatoes, buttermilk and 1 clove of minced garlic into a large mixing bowl and toss together. Allow mixture to sit for 30 minutes.
    • Line the bottom of the cake pan with a single layer of potato rounds. Some overlapping is okay.
    • Sprinkle the top with some garlic, rosemary and parmesan. Season with salt and pepper and continue layering gratin until all ingredients have been used.
    • Tightly cover with foil and bake for 25 to 30 minutes or until fork tender. Remove foil and invert onto an oven safe dish. Sprinkle top with parmesan.
    • Turn oven onto broil and return gratin back to oven. Broil for 2 to 3 minutes or until cheese is bubbling and top has crisped up.
    • Allow gratin to cool for at least 8 to 10 minutes before slicing and serving.

      NOTES  

    • **Tips: You want to get rid of any excess liquid as you build the gratin (by shaking off each disc of potato), this will help keep the gratin together as you flip it over and un-mold. Also, make sure to un-mold gratin carefully and place directly into the oven (on an ovenproof plate) to caramelize, as the gratin will be rather loose when inverted and needs to caramelize a bit to hold together….the additional grated parmesan should help too!

      Love your blog and have been a fan for some time. The glasses issue… I have been wearing glasses since I was little. Not sure if you experience the same issue, but I have a very small nose bridge (I am Asian). I find that some eyeglass shapes cause me to fog up more if they are closer to my face (e.g. plastic frames). Try a different frame shape (straight across the nose instead of curved) or frames with nose pads.

      There is no good solution for it except to get contacts if it really bothers you, at least that was my answer.

      PS can’t wait to try the gratin

      I’m an optometric technician and this is the best (though still not perfect) solution that I can come up with. I don’t know what type of glasses that you have, but I recently got a pair of frames with pretty big lenses. My big lenses fog up a lot more than my smaller ones did due to lack of air-flow–it drives me com-plete-ly insane! So I understand. Some of it is just dealing with it but there are some solutions. Try these wipes!

      I am an optician and there is a product called optifog but it has to be applied when the lenses are manufactured. It does work!

      I usually just lift my glasses up off my cheeks for a minute and fan towards my nose quickly with the other hand…. thankfully, they take on heat change shortly and your fog shouldn’t last too long! I know what you mean, I get warm easily too, especially at parties if there is drinking/a room full of people/lots of laughter or maybe any awkwardness, and my glasses fog right up like some kind of spy gadget. You should post a picture (non-fogged)! I bet you’re adorbable in your specs.

      LOVE the looks and sound of this dish and am so pleased you’re sharing Thanksgiving ideas! I’m always torn when it comes to vegetable sides……. I WANT THEM ALL

      I’m an Optician and we recommend only cleaning them with soap and water, or lens cleaner. Anything with harsh ingredients will affect the anti-glare coating on your glasses. There are many anti-fog cleaners out there that work pretty well which can help reduce the fogginess when you’re cooking. Also, you can go to your Optometrist’s office and have them adjust your glasses so they’re not sitting so close to your face which will reduce heat exposure to your skin. Good luck and I love your blog! xx

      This recipe sounds yummy! As for fog on glasses, my solution is contact lenses :^) Seriously, it’s one of the things I love about wearing contacts – no fog and no yearning for windshield wiper when it rains. I’m no help.

      yum this looks amazing.

      as a swimmer, i rub spit in my goggles to keep them from fogging, but you probably don’t want to do that to your glasses…

      Call your optometrist. If I remember correctly there is an anti fog coating they can put on your lens. I think atheletes who wear protective eye wear definitely have that put on their lenses. Good luck! Srumptious post! Thank you!

      Yummy looking dish! Since you have a special coating on your lenses I would ask the eye place about controlling the fogging issue. Ruining the coating would be a shame. Addressing the heat from another angle, it would be indelicate to ask your age but since perimenopause starts at age 34 for most American women addressing hot flashes seems to do the trick for me. Check out the homeopathic section at your supplements store. Harmless and effective. Any skiers or snorkelers out there with brilliant hints?

      First, this dish looks amazing and I plan to make it ASAP. But as a fellow glasses person, I thought I’d sympathize with the fog-issue. Generally, it’s not a big problem with me, but my glasses do fog if I go into a really warm room from the very cold (as in, into a bar from walking outside in the middle of january) or sometimes at the gym (when I am too lazy to put contacts in before heading to the gym). In general, if you can lift the glasses off your nose before the temp swing, that seems to help (I think diverting the heat from your breath is helping there), and also just moving your glasses down your nose a bit may help. Good luck!

      Just realized I answered the wrong question. I thought you meant the fogging that occurs when you open the oven door. I have no answer as to how to prevent it when your face warms up so hope your other readers are more helpful.

      Hi this looks so gorgeous. Im going to try tomorrow with pot roast guinea fowl.
      Try a drop of washing up detergent onto your lenses wiping clear with a tissue.

        Whatever you do, don’t put detergent on glasses! It’ll take the coatings off – any strong cleaning fluid will do this. I’d also avoid vinegar.

        The various coatings they put on glasses lenses are strong, but not to chemicals that attack surfaces (such as detergents – non anionic surfactants, if you’re feeling technical)

        The best cleaner is, generally, water and a microfibre cloth. Nothing else! Specialist glasses cleaner if you must.

        You can get antifog sprays (for motocycle helmets and similar) – but it’d be worth checking with your opticians whether they’re okay to use on your glasses. Ruining the coating can create a permanent mist on the lenses!

      You had asked about keeping your glasses “fog” free.. try cleaning them with vinegar, straight vinegar, no water.

      Works for me…
