Croissants have crossed global barriers to become a widely consumed pastry, unique for its rich buttery taste and crispy exterior. Regardless of location, the croissant production process involves creating laminated dough by repeatedly folding and rolling butter into dough. Temperature regulation is crucial to the croissant making process as too warm temperatures negatively affect the overall outcome.

Why is lamination important in the croissant making process?
An ideal croissant has a flaky exterior and a delicate honeycomb appearance on the inside. These are direct outcomes of the process of laminatin. During lamination, producers fold and roll butter into the dough to create multiple super-thin layers of dough. The fold pattern could be an envelope fold, single, letter, or book-fold. They can achieve this on a large scale production line with the help of bakery equipment such as a professional dough sheeter. Dough laminating ensures that open pockets form in the interior as the croissant bakes while the exterior develops uniform flaky stripes.
Varieties of croissants made from a croissant making equipment
Croissants come in two major forms; the straight croissants and the c-shaped or crescent-shaped ones. Although these shapes appear to reflect a baker’s choice and creativity, they actually represent the key ingredients in the croissant.
Generally, straight croissants contain 100% butter, while curved ones contain other fats such as oil or margarine. To create these varieties, bakers alter the cutting and rolling pattern of the dough. They could cut them into triangles or rectangles and might either roll or leave the edges straight. It’s important to ensure the dough is protected from heat during this process because too much heat will melt the butter and ultimately affect the texture of the croissant.
Croissants for vegans
Even though croissant making equipment will generally include ingredients like butter, milk, and eggs to create the ideal croissant, vegans can still enjoy this product by using plant-based alternatives to butter, eggs, and milk. Vegan butter, which is a combination of water and a plant-derived oil like olive or avocado, can help to achieve a buttery and chewy croissant. Olive oil and coconut oil are good substitutes for egg wash because they provide uniform browning. Dairy-free milk from almonds and oats does the job of providing a gorgeous sheen to the croissants.
The role of proofing when making croissant
Proofing is a crucial step in baking food items like croissants, which require incorporating air pockets into the mixture. During this stage, which is usually after cutting the doughs into shapes, the yeast cells release carbon dioxide gas after consuming sugar. This step is vital to achieving the optimal texture of the croissant. If it is over-proofed, the laminated layers will separate and cause the butter to leak out. On the other hand, under proofing creates a very dense croissant. Generally, achieving ideal proofing in frozen croissants is challenging because ice crystals form in the dough and affect yeast viability. However, a freezing rate of ≥ −3.19 °C min−1 is suitable to achieve the desired texture.
