  24. Hi Marilyn, I would love to try your key lime cheesecake. It looks fab. But limes are so hard to buy here and when we can they are extortionate in price and sad hard specimens. Pinning just in case I ever find decent and affordable limes!

    Thank you for linking up with the #MMBC.

    • I am sorry to hear that about limes. If you can use the squeeze lime juice in the dairy/produce area and skip the zest (peel). Or if you like use lemon. I do hope you get to sample something similar. The topping of a filling like this is what makes the etaste. Have a wonderful week!

  38. I’m with all your other readers who’ve checked in: a weakness for key lime anything. I’m not as crazy about cheesecake–i might try this with a thinner layer of cheese cake but the full topping key lime custard.

    • This cheesecake recipe is light and fluffy. It isn’t the heavy New York style of cheesecake. A piece will not cause a full overstuffed feeling. Go ahead and cut that layer in half. But I bet you will add more the next time. Personally, I would double the topping because for me that had the most flavor. Enjoy!

    • That’s funny Trish!! I never know how to tag cheesecake. As a cake? As a pie?? I think most of my recipes here switch back and forth! Thanks for visiting me. Have a great day.
