How to Make Lemon Slices? What's the Connection Between the Mafia and Coffee? Why is Sicily Rich in Lemons?

The Connection Between Lemons and the Mafia

Italy gave the world espresso — and, less glamorously, the Mafia. Curiously, one coffee-based snack has ended up tangled in Mafia lore. Simple, delicious, and refreshing, it was said to be the favorite treat of Mafia members: the Lemon Zest Slice.

The Historical Connection

What does a lemon-coffee snack actually have to do with the Mafia? This dessert got its fame partly from a Taiwanese variety show called "Kang Xi Lai Le," and while a link to the Sicilian Mafia is often claimed, documented evidence is thin. What we can do is reconstruct the story from Sicilian history itself. Before the 19th century, lemons were grown mainly for decoration and perfume. A yellow fruit that is little more than sour and astringent was simply not something anyone wanted to eat.

That changed when scurvy outbreaks revealed how vital lemons were — and citrus fruits in general. Because citrus is exceptionally rich in vitamin C, lemons and their relatives became the most sought-after fruits in 19th-century Europe. Sicily, which had long produced wine, wheat, and olives, began planting lemons too. Before long, lemons were generating serious cash income for the island. But the good times didn't last. The huge profits attracted every kind of criminal — thieves and bandits who would strip the orchards overnight the moment the lemons ripened, wiping out a farmer's entire year of work in a matter of hours. At the same time, Sicily was under military occupation by mainland Italy, and it was against this backdrop that the Mafia was born. Sicilian farmers began hiring the Mafia to guard their lemon groves — and that is how lemons and the Mafia became entwined.

From there, it is easy to imagine how the Lemon Zest Slice became associated with the Mafia and even a favorite among its members. When you are standing guard over a lemon grove all night, a refreshing, energizing snack is exactly what you need. So next, FrontStreet Coffee will show you how to make it.

How to Make Lemon Zest Slice

This is not clickbait — the recipe really is astonishingly simple. So simple that the cover picture alone tells you almost everything: lemon slices, coffee, and sugar. Combine them, and you have a Lemon Zest Slice. But knowing how to make it is not the same as making it well, so a few ingredient choices matter.

About Lemons

Here is a common misconception: many people assume the bitterness in lemons comes from the peel. It doesn't. The main source of bitterness is the seeds. So the easy route is to pick seedless lemons when shopping. If you end up with seeded ones, just remember to remove the seeds after slicing.

About Coffee Beans

The lighter a coffee bean is roasted, the denser it becomes — and the denser the bean, the less it snaps when you bite it. In plain terms: it is hard to chew, which is bad news for anyone with dental concerns. For a Lemon Zest Slice, dark roasted coffee beans are the better choice. They are crisp and easy to chew, and their bitterness creates a clean contrast against the lemon and the sugar. (This applies to the ground-powder version too.)

About Sugar

If you have brown sugar on hand, FrontStreet Coffee recommends using it. Brown sugar brings a deeper sweetness and adds another layer to the dessert. No brown sugar? No problem — just be generous with white sugar, like we are.

Preparation Steps

Here is how FrontStreet Coffee makes it. First, slice the lemon into moderately thin rounds. Too thick, and the peel's astringency takes over and ruins the experience. Too thin, and the lemon gets buried under the coffee and sugar. Moderate thickness is just right.

Then sprinkle sugar and freshly ground dark roast coffee over the slices in turn (whole beans work too, but they are far less convenient to eat). Grind the coffee to the same coarseness you would use for regular hot brewing.

At this point you can simply eat it as is and enjoy the most honest version of the ingredients. Or you can take it one step further: grab a kitchen torch and caramelize the sugar on the lemon surface until golden brown. (Just remember — coffee powder first, then the sugar layer.)

The Taste Experience

Seriously — try this. One bite gives you the bounce of lemon fiber, the crunch of roasted coffee, and the granular texture of caramel; on texture alone it is remarkably layered. Then comes the flavor: as you bite down, juice floods out, but the sugar tames the lemon's sharp acidity into something gentle and sweet. And here is the finishing touch — when you chew through the coffee, its lightly roasted bitterness cuts cleanly against the sweet-tart lemon juice. Distinct, but never jarring. It is genuinely wonderful. Go make it at home.

FrontStreet Coffee Recommendation

Since this snack calls for dark roasted beans — and since dark roasts are the backbone of Italian-style coffee — here are a few FrontStreet Coffee beans that fit the bill beautifully, in the cup or on the plate.

FrontStreet Classic Blend — Designed specifically for espresso and moka pot brewing, this blend's standout strength is its abundant crema: even a beginner with a non-professional home machine can easily pull a dense, velvety shot. Built on the traditional Mamba blend formula with a touch of Robusta added to an old-school Italian recipe, it delivers the aroma of butter, nuts, spices, dark chocolate, and toast — a wild, full-bodied mouthfeel crowned with rich golden crema that makes latte art effortless. Full-bodied and smooth, it suits veterans and newcomers alike, at home or in a café.

FrontStreet Premium Blend — The longest-serving espresso blend in FrontStreet's own shops, in duty for nearly ten years behind core drinks like Americanos and lattes. It pairs Brazilian Cerrado and Colombian Huila beans: the Brazil gives a comfortable sweet-bitter note and a creamy peanut fragrance with an exceptionally smooth entry, while the Colombia contributes nutty, chocolate, and caramel aromatics with a pleasant acidity — the classic, familiar taste of Italian-style coffee. Works equally well for home or commercial use.

FrontStreet Brazil Queen Estate SOE — Low acidity, a soft gentle body, and an approachable price have long made Brazilian coffee a first pick for specialty espresso, offering chocolate, nut, and cream aromas with a balanced profile that aids extraction stability. This single-origin lot from Queen Estate is an unusual Yellow Bourbon with a quiet, sweet character; roasted medium-dark and pulled on an espresso machine, it shows lovely notes of butter cookies, macadamia, and toasted bread — a fine match for anyone who loves that deep, roasty flavor in their dessert.
