In the tropical climate of the Yucatán Peninsula, there are three different types of lime, and too many other citrus varieties to count. But really, this tart dessert was born in the United States as the ever-reliable lemon square. At Hartwood, the Mexican-modern-American restaurant in the beach town of Tulum, the crust is made with grated piloncillo, the traditional sugar there. (Raw sugar stands in nicely for home cooks elsewhere.) The crust is also scented with chamomile, which grows in huge thickets in the Yucatán. Adding half a cup of sweetened shredded coconut to the dough for the crust is also a nice touch. —Julia Moskin

Lime Squares With Raw Sugar Shortbread Recipe (2)

Preparation

  1. Make the crust: Combine flour, sugar and salt in a bowl and toss to combine. Rub in butter until dough comes together in clumps; add a trickle of cold water if mixture seems dry. Press dough into a 9-by-13-inch baking pan. Prick all over with a fork and refrigerate for at least 30 minutes, or overnight.

  2. Step

    2

    Heat oven to 350 degrees. Bake chilled dough until golden and toasted, 15 to 20 minutes. Leave the oven on.

  3. Step

    3

    Meanwhile, make the topping: Sift flour and chamomile together, using the sifter to break up clumps and chamomile flowers. Repeat to eliminate any chamomile leaves or buds.

  4. Step

    4

    Strain the lime zest from the juice; discard zest. In a bowl, whisk eggs together. Slowly whisk in strained lime juice, sugar and salt. Add dry ingredients and mix well.

  5. Step

    5

    Pour topping over crust and bake for 20 minutes, then check to see if filling has set. If loose, bake another 5 minutes and check again. (Keep in mind that the filling will continue to thicken as it cools.) Once cooled, cut into squares or bars. Serve dusted with chamomile flowers.

This was a big hit with friends, and with a lime lover like myself, for Cinco de Mayo. In my experience, though, some limes are juicier than others. To those yet to make this recipe, be prepared and have extra limes on hand. Also, the raw sugar for the crust doesn't make it super sweet, which is nice. (I grated piloncillo, since I could find some, but will speed things along next time by sticking to turbinado.)

rachel

Wondering if the chamomile is meant to be added to the flour in the crust? It's listed as an ingredient for the filling but the recipe description indicates otherwise. Thanks!

Eric Rodgers

I had wondered that too as I made these the first time. Generally, I'm no fan of chamomile, so I didn't kick in extra for the crust. Having tried them once now, I could see adding a tea bag's worth without risk of overkill.

Amanda Paschke

The amount of butter seemed a bit off, like there should have been more. The crust was dry and crumbly, not like a typical shortbread dough. Still, it was tasty. I might add more butter next time.

jessica

I did not use chamomile. Next time make crust much thinner. Maybe increase filling quantity.

Shanster

I have their cookbook, and the crust for this recipe has 2 cups of flour, 1/4 cup of sugar, and 1 1/2 sticks of butter. I haven't made the recipe yet, but based on the comments, I think I'll try that ratio instead of what's published here. I had a similar tart at the restaurant and it was DELICIOUS, so I can't wait to try this! It will be hard to match the flavor of the wood-fired oven, though . . .

L

Half the crust. Didn’t use camomile and was still pretty good

Beth

Might there be a suggestion for a substitution for dried chamomile (tea or otherwise)? I'm allergic to it. Hives. Sounds good otherwise! Love lime.

Betsy M

Based on other comments I used more butter, less flour for crust: 1 cup whole wheat pastry flour,1 cup all purpose flour, 3/4 cup melted butter. As I recall, I did the topping as directed, except I didn't bother with the zest (the skin of my limes was too thin to zest). Delicious!

hendrik

How do you get the nice shiny brown crust ? mine was pale. Still have to taste it. ....

Talia

The flour to butter ratio is way off--crust was too dry and crumbly and ratio of crust to filling was also way off, filling barely covered the crust. Filling was also way too gooey and not very tart, I would completely remove the flour from the filling in order to get the tartness and freshness that I expect of a lime / lemon bar.

DJ

One more thing—The “zest” is only the outer covering/rind containing the oils of citrus. A microplane can be used to take off just a sliver...any further into the rind, and it will taste bitter.Also, pulp is to be strained out. Not zest—as it is incorrectly used here.I made it once without straining, and it does taste better if you strain it out.👩🏻‍🍳

DJ

Definitely needed more butter than was called for—in the shortbread.The lime custard on top was wonderful!!!I grated a tiny bit of zest into lime juice before mixing into eggs.

Melissa

Why does the ingredients list specify that the lines should be zested and juiced, both mixed together, the later the zest is strained out? Seems like a lot of extra work for a possible slight addition of like flavor to the juice...

S mattes

I too found crust a bit dry, even with the additon of coconut. How much would you add to address dryness?I found the thickness just fine.

Merry

Can these be made in advance and frozen?

Lyn

I did not have raw sugar so used coconut palm sugar instead. Crust was delicately sweet but too thick. I used a combination of chamomile and mint which blended well with the lime. Nice and tangy, just the stuff for lime lovers. The red and yellow chamomile flecks lend a festive look.

jessica

The amount of butter seemed a bit off, like there should have been more. The crust was dry and crumbly, not like a typical shortbread dough. Still, it was tasty. I might add more butter next time.

S mattes

How much butter would you add, or could you reduce the amount of flour? Other shortbread recipes call for the same amount of butter and sugar, but much less flour.

rachel

Sandy

The way I read it, the chamomile and flour are sifted together at Step 3, and then mixed in as "the dry ingredients" component of the filling at Step 4.

FAQs

What is the mistake in making shortbread? ›

The most common mistakes when making shortbread are over-working the dough, and incorporating too much flour.

Why is shortbread unhealthy? ›

However, lipids, which are a component to food such as shortbread cookies are considered unhealthy because they are the most energetic nutrients in food and are a source of saturated fatty acids (SFA) (usually 40%) and sometimes also trans fatty isomers (TFA) [4,5,6].

What happens if you don't chill shortbread dough? ›

But in this shortbread cookie recipe, it really makes a difference. Chilling the dough helps the cookies hold their shape. If you don't chill your shortbread dough, the cookies will spread as they bake.

What to do with too many fresh limes? ›

If you've got lots of limes, the sky's the limit! Make homemade limeade, a sweet tart tangy treat that's positively delightful, or whip up a margarita if you love co*cktails. Lime is perfect in dressings, sauces and vinaigrettes, or make it into a main dish dinner that will feed the whole family.

Can I freeze whole limes? ›

Sure can! Place whole limes in a freezer safe bag like Glad® Flex'n Seal® Freezer Quart Bags, squeezing as much air out as possible. Placed in the freezer, limes will keep 4–6 months. Just in lime for all your favorite citrus-based treats!

Can limes be eaten raw? ›

Limes are rarely eaten raw, except when used as a garnish, and your dentist will tell you that if you like to suck your limes after drinking that margarita, you should follow it up with a glass of water as the high acid content can damage tooth enamel.

What not to do when making shortbread? ›

The key with shortbread is not to overhandle it. Make the dough exactly as instructed, but don't mess around making shapes or over rolling the dough - you will end up with delicious but tough biscuits. Stretching and pulling the dough activates the gluten in the flour, making chewy cookies and not crisp ones.

Why did my shortbread fail? ›

There are a variety of reasons why the shortbread could be damp underneath but it is most likely that either the dough is being pressed out too thickly, the pan is not metal so heats up too slowly, or the oven temperature is too high causing the top to brown before the bottom has cooked sufficiently.

What are the disadvantages of shortbread? ›

Sugar provides a fast source of energy. There are rarely any artificial additives. Cons: Shortbread is a weight watcher's nightmare because it is extremely high in saturated fat and calories.

What happens if you over mix shortbread? ›

It's important to avoid over-mixing shortbread dough, which will develop gluten and make the finished product tough, not tender. To make sure that the flour mixes completely with little effort, sift the flour first to get out all of the lumps.
