How to Grind Cinnamon Sticks: 5 Effective Methods

The most effective ways to grind cinnamon sticks include using a dedicated coffee grinder (best for fine powder), spice grinder, mortar and pestle (for small batches), or even a microplane grater. For optimal results, break sticks into small pieces first, work in small batches, and store freshly ground cinnamon in an airtight container to preserve its volatile oils and intense flavor.

Grinding your own cinnamon sticks transforms your baking and cooking with superior flavor and aroma compared to store-bought powder. Commercially ground cinnamon often loses its essential oils during processing and storage, resulting in diminished potency. When you grind cinnamon sticks at home, you access the full spectrum of its warm, complex flavor profile that elevates everything from apple pie to chai tea.

Why Freshly Ground Cinnamon Makes a Difference

Cinnamon sticks contain essential oils that begin evaporating as soon as they're ground. Pre-ground cinnamon found in supermarkets typically loses 60-80% of its aromatic compounds within six months of processing. By grinding your own sticks, you preserve these volatile compounds, resulting in noticeably brighter, more complex flavor. This difference is particularly important in recipes where cinnamon plays a starring role rather than just a supporting note.

5 Effective Methods to Grind Cinnamon Sticks

Each grinding method offers different results in terms of texture, convenience, and flavor preservation. The best approach depends on your available tools and intended use.

Method	Best For	Texture Result	Preparation Time
Coffee Grinder	Daily use, fine powder	Ultra-fine, consistent	2 minutes
Spice Grinder	Regular spice preparation	Fine to medium	3 minutes
Mortar and Pestle	Small batches, traditional method	Coarse to medium	5-7 minutes
Microplane Grater	Quick small amounts	Fine powder	2-3 minutes
Blender/Food Processor	Large batches	Medium to coarse	4-5 minutes

Detailed Grinding Techniques

Using a Coffee Grinder (Best Overall Method)

Repurposing an old coffee grinder exclusively for spices yields the finest, most consistent cinnamon powder. First, break cinnamon sticks into 1-inch pieces using kitchen shears or by tapping gently with a rolling pin. Work in small batches (about 10-15 pieces at a time) to prevent overheating. Pulse for 20-30 seconds until powder forms. Let the grinder rest for 30 seconds between batches to prevent heat buildup that can degrade flavor compounds. After grinding, immediately transfer to an airtight container.

Spice Grinder Method

Dedicated spice grinders work similarly to coffee grinders but often have more powerful motors designed specifically for hard spices. The process remains the same: break sticks into small pieces, work in small batches, and pulse until desired consistency. Spice grinders typically produce slightly coarser powder than coffee grinders, which some prefer for certain applications like mulled wine where a bit of texture is acceptable.

Mortar and Pestle Technique

For those seeking a traditional approach without electric appliances, the mortar and pestle method preserves maximum flavor as it generates minimal heat. Start by breaking sticks into very small pieces (1/4 inch). Place a few pieces in the mortar and apply firm, circular pressure with the pestle. This method requires patience but yields excellent results for small quantities. Expect to spend 5-7 minutes to produce one tablespoon of powder. The resulting texture will be slightly more uneven than machine-ground cinnamon, which can be desirable in certain recipes.

Microplane Grater Approach

When you need just a small amount of cinnamon powder quickly, a microplane grater offers surprising effectiveness. Hold the cinnamon stick firmly and rub it against the grater using downward motions. This method works best with thinner, more flexible cinnamon sticks. The resulting powder is exceptionally fine and aromatic, though this technique produces smaller quantities than other methods. Wear food-safe gloves to prevent cinnamon oils from irritating your skin during this process.

Blender or Food Processor Method

While less ideal than dedicated grinders, blenders can handle larger quantities of cinnamon sticks. Break sticks into small pieces and add to the blender with a tablespoon of rice flour or cornstarch (this absorbs moisture and prevents clumping). Process on high for 30-45 seconds, then let rest for 1 minute before continuing. This method produces a coarser grind that works well for recipes where texture isn't critical, like in spice blends or mulled beverages.

Pro Tips for Grinding Cinnamon Sticks Successfully

Several factors influence the quality of your ground cinnamon. Understanding these elements helps you achieve optimal results every time:

• Dry your sticks first: If your cinnamon sticks feel slightly moist, spread them on a baking sheet and dry in a 200°F oven for 10 minutes before grinding
• Work in small batches: Overfilling your grinder creates uneven results and generates excess heat that degrades flavor
• Cool between batches: Let your grinder rest for 30 seconds between batches to preserve volatile oils
• Store properly: Transfer freshly ground cinnamon to an airtight container immediately and store in a cool, dark place
• Grind just before use: For maximum flavor impact, grind only what you need for immediate use when possible

Common Mistakes to Avoid When Grinding Cinnamon

Many home cooks encounter issues when first attempting to grind cinnamon sticks. Learning from these common pitfalls ensures better results:

• Using a grinder that previously processed coffee or other strong-flavored items (always dedicate a grinder exclusively to spices)
• Grinding too large a quantity at once, which causes overheating and inconsistent texture
• Not breaking sticks into small pieces first, making the grinding process more difficult
• Storing ground cinnamon in transparent containers where light degrades quality
• Using excessive force with manual methods, which generates heat that diminishes flavor

Storing Your Freshly Ground Cinnamon

Proper storage maintains the superior quality of your homemade ground cinnamon. Transfer powder to an airtight glass or metal container immediately after grinding. Store in a cool, dark cupboard away from heat sources. Properly stored, freshly ground cinnamon retains peak flavor for 3-4 months, compared to 6-12 months for whole sticks. Label your container with the grinding date to track freshness. For extended storage, consider freezing in an airtight container (thaw before opening to prevent condensation).

Frequently Asked Questions

Can I grind cinnamon sticks in my coffee grinder?

Yes, but dedicate a coffee grinder exclusively to spices. Coffee grinders produce the finest powder, but residual coffee oils will contaminate your cinnamon's flavor if you use the same grinder for both. Clean thoroughly between uses if you must share a grinder.

How fine should ground cinnamon be for baking?

For most baking applications, cinnamon should be ground to a fine powder consistency similar to store-bought ground cinnamon. This ensures even distribution in batters and doughs. Ultra-fine powder works best for delicate recipes like custards or meringues, while slightly coarser grind suits heartier applications like spice cakes.

Why does my homemade ground cinnamon taste stronger than store-bought?

Freshly ground cinnamon contains higher concentrations of cinnamaldehyde and other volatile compounds that degrade over time in pre-ground products. This results in more intense, complex flavor. When substituting homemade for store-bought, start with 25-30% less and adjust to taste.

Can I use a blender to grind cinnamon sticks effectively?

Yes, but with limitations. Blenders work best for larger quantities and produce coarser results than dedicated spice grinders. Add a small amount of rice flour to absorb moisture and prevent clumping. Process in short bursts with cooling periods between to prevent heat buildup that degrades flavor compounds.

How long does freshly ground cinnamon last compared to whole sticks?

Whole cinnamon sticks retain peak quality for 1-2 years when stored properly, while freshly ground cinnamon maintains optimal flavor for 3-4 months. The grinding process exposes more surface area to air and light, accelerating the degradation of volatile oils. For longest shelf life, grind only what you need for immediate use.
