Luscious Pistachio Cream Filling

This pistachio cream recipe transforms ordinary pastries into elegant Italian treats worthy of a high-end pasticceria. The silky texture and nutty flavor create a decadent filling that elevates any dessert it touches, especially traditional zeppole.

I discovered this recipe during my culinary travels through Sicily and have been perfecting it ever since. What began as a special occasion treat has become my signature dessert for family gatherings.

Ingredients

• Prepared crema pasticcera: Half of a full recipe, chilled for proper consistency and easier folding
• Heaping tablespoon of pistachio cream concentrate: Delivers intense authentic flavor without overwhelming sweetness
• High quality heavy whipping cream: With highest fat percentage possible, creates stable peaks and luxurious mouthfeel
• Tablespoon of powdered sugar: For light sweetness that doesn't disturb the silky texture
• Unsalted chopped pistachios: Add textural contrast and visual appeal
• Optional green food coloring: Enhances presentation without affecting flavor

Step-by-Step Instructions

Combine the bases:

Take your chilled pastry cream and gently fold in the heaping tablespoon of pistachio cream concentrate. This is where the distinctive nutty flavor develops. If using food coloring, add just two drops now for a subtle green hue that suggests pistachio without looking artificial. Fold with a light hand to maintain the airy texture of your base.

Whip the cream:

In a chilled bowl, combine the heavy cream and confectioners sugar. Whip until very stiff peaks form. This might take longer than you expect but patience ensures proper structure. The cream should be firm enough to hold its shape when the beater is lifted but still glossy. Properly whipped cream creates stability in the final product.

Create the final cream:

Gently fold the whipped cream into the pistachio pastry cream mixture using a spatula with a down across up and over motion. Continue until the color is completely uniform with no streaks remaining. The texture should be light but stable enough to pipe through a pastry bag without collapsing.

Assembly:

Fill your zeppole centers with plain pastry cream as a flavor foundation. Then pipe the pistachio cream on top in decorative swirls using a star tip for professional presentation. Finish by sprinkling with chopped pistachios for both visual appeal and textural contrast.

The pistachio cream concentrate is truly the secret ingredient here. After trying countless variations, I discovered that using a high-quality imported Italian pistachio paste creates an intensity of flavor that simply cannot be achieved with extracts or ground nuts alone. My grandmother actually wept when she tasted this cream, saying it reminded her of childhood visits to her favorite pasticceria in Bronte.

Storage Instructions

This pistachio cream can be refrigerated for up to three days in an airtight container. The flavor actually improves after 24 hours as the pistachio notes deepen and meld with the cream. Just give it a gentle stir before using if it's been sitting for more than a day. I do not recommend freezing as the texture can become grainy upon thawing.

Finding Pistachio Cream

The most challenging aspect might be sourcing authentic pistachio cream. Look for products labeled "crema di pistacchio" from Sicily if possible, particularly those from Bronte which is famous for its intense green pistachios. If unavailable locally, specialty Italian food shops online carry excellent options. Avoid products with artificial coloring or excessive added ingredients; the simplest versions with just pistachios, sugar and perhaps a touch of oil produce the best results.

Variation Ideas

While this recipe is designed for zeppole, its versatility makes it perfect for numerous applications. Try it as a filling for cream puffs, layer it between sponge cake, use it as a cannoli filling, or simply serve it in elegant glasses topped with crushed amaretti cookies for a quick dessert. For summer gatherings, I often sandwich it between two vanilla wafer cookies and freeze for impromptu ice cream sandwiches with sophisticated flavor.

Frequently Asked Questions

→ Can I make this pistachio cream in advance?

Yes, you can prepare this pistachio cream up to 2 days in advance. Store it in an airtight container in the refrigerator. For best results, give it a gentle stir before using to restore its consistency.

→ What is cream of pistachio and where can I find it?

Cream of pistachio (also called pistachio paste) is a concentrated paste made from ground pistachios. You can find it in specialty food stores, Italian markets, or online. Alternatively, you can make your own by blending toasted, unsalted pistachios with a small amount of neutral oil until smooth.

→ Can I skip the food coloring?

Absolutely. The green food coloring is optional and only enhances the visual appeal. The natural pistachio paste will provide a subtle green hue, though less vibrant than with food coloring.

→ What desserts can I use this pistachio cream for?

This versatile pistachio cream works beautifully in many desserts beyond zeppole, including cream puffs, éclairs, layer cakes, tarts, as a macaron filling, between cookies, or even as a topping for pancakes and waffles.

→ Why does the recipe specify high-fat heavy cream?

Higher fat content in heavy cream (ideally 36-40% fat) creates a more stable whipped cream that holds its shape longer and provides a richer mouthfeel, resulting in a more luxurious final product that won't collapse or weep.

→ How do I achieve the perfect consistency for piping?

For an ideal piping consistency, ensure your pastry cream is properly chilled before mixing, whip the cream until very stiff peaks form, and fold the ingredients together gently but thoroughly. If the mixture seems too soft, refrigerate for 30 minutes before piping.
