What is the gel on fruit tarts?

The delicious, shiny gel topping found on fruit tarts is an important part of the dessert’s appeal. This clear glaze not only enhances the look of the tart, but also serves several functional purposes like protecting the fruit, adding sweetness, and bringing all the components together into one cohesive dessert. But what exactly is this magical gel that makes fruit tarts so irresistible?

What is Fruit Tart Gel Made Of?

The gel used on fruit tarts is typically made from just a few simple ingredients:

  • Sugar – Usually granulated white sugar, which provides sweetness.
  • Water – The liquid base that dissolves the sugar.
  • Cornstarch – A thickening agent that gives the gel its glossy, smooth texture.
  • Flavorings – Often fruit juice, extracts, zest, or liquor to complement the fruit.

Fruit tart glaze relies on a straightforward sugar syrup base. Granulated sugar is heated with water until completely dissolved into a simple syrup. Cornstarch is whisked into the hot syrup until smooth and allowed to boil for 1-2 minutes. This cooks the cornstarch and causes the mixture to thicken into a glossy gel.

Flavorings like fruit juice, purees, extracts, zests, and liqueurs can be added to the basic syrup to infuse it with flavor that complements the tart filling. For example, lemon or orange juice and zest are commonly used in citrus tarts. Almond extract or amaretto liqueur work well with stone fruit fillings. The possibilities are endless!

Why Use a Gel Topping on Fruit Tarts?

The gel coating on fruit tarts serves several purposes:

Enhances Visual Appeal

The clear, shiny, smooth glaze is very eye-catching and makes the fruit tart look professionally finished. It shows off the colors of the fruit and makes the tart look polished and appetizing.

Adds Sweetness

Since the gel is made primarily of sugar syrup, it makes the tart a bit sweeter when eaten. The sweetness balances nicely with the natural tartness of the fresh fruit.

Prevents Drying

The gel seals in moisture and prevents the fruit slices and tart shell from drying out. This helps keep the tart tasting fresh.

Extends Shelf Life

Sealing the fruit in a protective gel barrier prevents oxidation and delays spoilage. This allows the fruit tart to be stored for a day or two.

Binds Components

The gel helps “glue” all the layers of the tart together neatly – the shell, filling, and artful fruit arrangements stay in place better when coated in gel.

Provides Texture Contrast

The thick, smooth gel contrasts nicely with the flaky crust and soft, tender fruit. The different textures make eating the tart more dynamic and interesting.

Makes Slicing and Serving Cleaner

The gel coating helps hold everything together so slices can be neatly cut and served without making a mess.

What Are Some Common Fruit Tart Gel Flavors?

Popular flavor choices for fruit tart glazes include:

Citrus

For citrus tarts, orange juice, lemon juice, lime juice, citrus zests, Triple Sec, Grand Marnier, or other citrus liqueurs are used.

Berry

Berry fruit tarts pair well with glazes made with berry purees, Chambord, cranberry juice, or other berry-flavored liqueurs.

Stone Fruit

Apricots, plums, peaches and nectarines work nicely with almond extract, amaretto, or Frangelico hazelnut liqueur.

Tropical Fruit

Pineapple, mango, banana, coconut, etc. are complemented by rum, Malibu, or tropical fruit juices.

Apple

For apple tarts, cinnamon and/or apple juice add nice flavor. Apple brandy like Calvados can also be used.

Neutral

Simple syrup with no added flavor allows the natural taste of the fruit filling itself to shine through.

So in summary, fruit tart gel can be flavored in many creative ways to match or accent the other components!

What is the Ideal Gel Consistency for Fruit Tarts?

The gel should coat the back of a spoon and have a thick, somewhat syrupy texture. However, it should not be stiff like a firm jelly. The gel should slowly drip off a spoon, allowing it to smoothly coat the fruit.

A gel that is too thin will pool beneath the fruit and be too runny. It will lack the glistening thickness ideal for fruit tarts.

If the gel is over-stiffened, it will be too firm to properly adhere to the fruit. It may slide right off the fruit when cut. Proper consistency is important for both visual appeal and functionality.

How Long Does Fruit Tart Gel Last?

The gel helps prevent the fruit tart from drying out, but it is still highly perishable and needs proper storage. An assembled fruit tart with gel topping can typically last 1-2 days refrigerated.

The gel itself can be made ahead of time and refrigerated for 3-4 days before use. Just reheat gently to liquify again before brushing onto the tart.

For longer storage, the gel can be frozen for 1-2 months. Thaw overnight in the fridge before using.

To maximize freshness, fruit tarts are best assembled only a few hours before serving. But the gel does help extend the window of freshness slightly longer.

How is Fruit Tart Gel Applied?

There are a few common methods used to apply gel neatly and evenly over the fruit:

Brushing

Using a clean pastry brush, the gel can be gently brushed over the top of the fruit till evenly coated. This gives nice control and layering.

Drizzling

The gel can be drizzled decoratively over the fruit in a zig-zag or circular pattern using a spoon or squeeze bottle.

Pouring

The entire tart can be placed briefly under a thin stream of gel gently poured from a measuring cup or pitcher. The gel will smoothly cover all the fruit.

Spreading

A small offset spatula makes it easy to spread the gel evenly over the fruit in an even layer.

No matter the application method, the key is to avoid excess pooling or uneven bare spots. Practice leads to the perfect glistening fruit tart gel finish!

Can Fruit Tart Gel be Colored?

Yes, fruit tart gel can be tinted with food coloring to create colorful effects. Gel food colorings work best as they will not dilute the thickness.

Possible ways to use colored gel include:

  • Tint different flavor gels different colors for a rainbow effect
  • Use pale pastel shades for a delicate springtime look
  • Make the gel match the fruit color for a monochromatic effect
  • Use white gel on red fruit for a striking contrast
  • Color just the borders leaving the center clear

When coloring gel, remember to use gels sparingly as it takes very little to achieve a vivid color. Too much can detract from the beautiful fruit. Subtle and pastel hues tend to work best.

Can Fruit Tarts be Made Without Gel?

While gel helps fruit tarts look and taste their best forserving, it is possible to prepare them without it. Here are some alternatives:

Glaze with Melted Jelly

Heated fruit jelly can be brushed on as a replacement glaze. However, jelly will have moresatiny shine versus the high gloss of specialized gel.

Omit Gel Entirely

The tart can be assembled with no gel topping at all. The fruit will still be anchored by the filling below. However, the look may be less clean and elegant.

Use Whipped Cream

Whipped cream can be piped decoratively around and over the fruit. This will provide a nice flavor counterpoint. However, the look will be less sleek.

Coat with Egg Wash

Brushing egg wash over the fruit will provide a light sheen. But it lacks the clarity and evenness of true gel.

Dust with Powdered Sugar

A light dusting of powdered sugar adds subtle sweetness and an understated sheen, but lacks the dramatic glaze effect.

So in summary, gel-free fruit tarts can certainly be created, but likely with some sacrifice to aesthetic appeal. Many professional bakers and pastry chefs would argue that gel is an indispensable fruit tart finishing touch!

Troubleshooting Fruit Tart Gel

Here are some common fruit tart gel problems and how to fix them:

Gel is Too Thin/Runny

– Increase the cornstarch thickener slightly
– Cook the gel mixture longer to evaporate excess moisture

Gel is Too Thick/Firm

– Add a bit more water to dilute
– Use less cornstarch next time

Gel Won’t Adhere to Fruit

– Brush gel onto fruit while both gel and fruit are still warm
– Ensure fruit surfaces are clean and dry before applying gel

Fruit is “Weeping” Moisture Through Gel

– Allow fruit to drain well on paper towels before topping with gel
– Use a bit more cornstarch to thicken the gel

Gel is Clouding Up or Losing Glossy Sheen

– Be sure to bring gel completely to a boil when cooking to activate cornstarch
– Do not refrigerate gel for more than 2-3 days as moisture may loosen texture over time

Fruit is Floating Up Through Gel

– Apply gel in thin layers, allowing each coat to set up slightly before adding more
– Chill the assembled tart before serving to help firm up the gel

White Spots or Residue on Gel Surface

– Ensure there is no egg wash or other residue on fruit before applying gel
– Clarify impure gel by straining through cheesecloth if needed
