    I never learned how to preserve food properly. I have bought drying rack to dry food and tried to dry mango and apple slices but I always prefer fresh fruits compared to dry ones. But I think it is always good idea to have some food preserve though. Informative post.

    Good article, Preeti. Other ways of preserving food include smoking (good for meats and tomatoes) and fermenting (for instance Sauerkraut). Very practical information. Lots of people are turning to raising and preserving their own food in these uncertain economic times!

    I love cooking so, I love preserving the food by canning. Specially after the fall harvest of tomatoes by making tomato sauce to use up later on pasta or lasagna dishes.

    I like that you used the video as canning is not well known for many.

    I simply am clueless when it comes to preserving food. The most I have done is freezing lentils which seems to be fine for now. My wife want to learn how to do canning so we can keep some food later without freezing, I will ask her to check out here.

  5. Monica @ Museum and More says:


    This is good idea, I use vacuum seal to preserve food, I have used drying as preserving fruits and tomatoes. Canning I tried once but it was bit complicated for me, I should try again after reading your post. Thanks for encouraging me.

  6. ZenGirl says:


    Vacuumsealing food works great, I have not used it as much. Canning can be time consuming but works very well. Good luck, let me know how it turns out.

  7. ZenGirl says:


    Freezing lentil and daal is good way for weeknight meals and works very well. I think you are doing well. Canning can be learned with little effort, although I am no expert myself and learning it. Good luck. hope your wife will like canning.

  8. ZenGirl says:


    Making tomato sauces to use up later is great idea. Looks like you love cooking which is great thing for being healthy and eating well. The video of canning is not by me and from you tube expert but I found through google search. I thought it might be useful to readers.

  9. ZenGirl says:


    Thank you for adding suggestions on smoking food and fermenting it. It is sure valuable input. I will add it the post. Yes, we can preserve food to save money, and eat well at the same time.

  10. ZenGirl says:


    Drying mango and apple seem like a good idea as you can munch on these dried fruits when you are on go. One does not need to do it all, but one or two methods will work too. I am glad you found this informative.

    I don’t do much preserving of food because I like to have mine fresh. However, I can understand the benefits of preservation. It aids in convenience and most certainly, preserving food ourselves is better than buying canned food from the supermarket. One ingredient that I preserve food with is using salt. I keep bottled ground chilli, added with salt, in my fridge.

  12. ZenGirl says:


    Fresh food is always best choice. However, if you want to eat some food out of season or on go, preserve food comes to rescue. For example, if you have garden and plenty of tomatoes left after you ate all you can, share all you can, one can make tomato sauce to use it later.

    I think salt is great preserver and you seemed to be doing well stocking up!

    I always love your practical and educational blogs, Preeti. We live in such a “throw away” society that it is empowering to be mindful of our food source. This is a great lesson of appreciation for all those things that we easily take for granted.

    Thanks for telling us how to preserve food. Many a times we waste food, which we can actually preserve it.
    To be frank I use drying and freezing for preserving food, but others methods you mentioned here, I do use.

  15. ZenGirl says:


    You’re too kind. Yes, we in America tend to throw away quite bit of food which can be used by us or other people. We do take food supply for granted here.

  16. ZenGirl says:


    Drying and freezing is great way to preserve food. I know many people preserve food in salt brine or oil by making various types of pickles in Korean, Indian and Many south Asian nations. Thanks for stopping by and commenting.

    What a timely post! Summer’s a great time to do some preserving, and although I can’t say I have ever done much of it, your tips are really great and will be of great use if I ever should. Thanks, Preeti!

  18. ZenGirl says:


    I am sure with your lovely cooking that you, there will hardly be any leftover for you to freeze or preserve to use later on! 🙂 I do little bit of preserving but not as much as some people, if you do, let me know how it goes.
