Ever wonder why your food costs seem off even though you're tracking ingredients carefully? Fresh and dried versions of the same ingredient create pricing puzzles that trip up most kitchen teams. Many restaurants estimate these costs and unknowingly lose money on every dish.
The difference between fresh and dried ingredients
Fresh and dried versions aren't just different weights - they're completely different products. A gram of dried oregano packs way more flavor punch than fresh oregano. So you can't use them gram-for-gram.
💡 Oregano example:
For a pasta sauce for 4 people:
- Fresh oregano: 8 grams needed
- Dried oregano: 2 grams needed
- Fresh oregano: €0.50/gram
- Dried oregano: €2.00/gram
Cost per 4 portions: Fresh €4.00 vs. Dried €4.00
Determining the conversion factor
Each ingredient has its own conversion ratio between fresh and dried forms. This factor tells you exactly how many grams of each version deliver the same flavor impact.
Common conversion factors:
- Herbs: 1 gram dried = 3-4 grams fresh
- Onion/garlic powder: 1 gram powder = 8-10 grams fresh
- Chili pepper: 1 gram dried = 5-6 grams fresh
- Ginger: 1 gram dried = 6 grams fresh
⚠️ Note:
Always test what works for your specific dish. Conversion factors are starting points, not gospel.
Cost price calculation per version
To figure out which version saves you money, you'll calculate costs per portion for both options. You need: purchase price per gram and required quantity per portion.
💡 Garlic example for 1 portion of soup:
Recipe calls for "2 cloves of garlic" = 6 grams fresh
- Fresh garlic: 6 grams × €0.08/gram = €0.48
- Garlic powder: 0.6 grams × €0.40/gram = €0.24
Savings: €0.24 per portion with powder
Seasonal price differences
Fresh ingredients swing wildly in price depending on seasons, weather, and availability. Dried versions stay more stable but can spike suddenly due to harvest issues in producing countries.
Track prices for both versions and switch between fresh and dried based on:
- Season: Fresh basil costs pennies in summer, dollars in winter
- Shelf life: Fresh ingredients demand faster turnover
- Supply reliability: Dried versions are always in stock
- Flavor profile: Some dishes specifically need fresh or dried
⚠️ Note:
Update cost prices monthly. Fresh ingredients can double between seasons.
Practical registration in your system
Register both versions as separate ingredients in your system, even though it's technically the same product. Based on real restaurant P&L data, this approach prevents costly recipe adjustments every time you switch versions.
💡 Registration example:
- "Oregano fresh" - €0.50/gram - 2 grams per portion
- "Oregano dried" - €2.00/gram - 0.5 grams per portion
- "Basil fresh" - €0.80/gram (summer) / €1.60/gram (winter)
- "Basil dried" - €3.20/gram - stable
A food cost calculator like KitchenNmbrs can register both versions and automatically calculate the cheapest option for your cost price.
How do you calculate purchase price per portion? (step by step)
Determine the conversion factor
Test how many grams fresh versus dried you need for the same flavor result. Note this ratio as a conversion factor (for example 1:4 for dried herbs).
Calculate cost per gram
Divide the purchase price by the number of grams in the package. For fresh ingredients: also account for waste (peels, stems). For dried: calculate with 100% usable weight.
Compare costs per portion
Multiply cost per gram by required quantity per portion for both versions. Choose the cheapest option, unless the recipe specifically requires fresh or dried.
✨ Pro tip
Create a monthly price comparison spreadsheet tracking your top 15 dual-version ingredients (fresh vs. dried). You'll spot cost-saving opportunities worth 3-8% on food costs within 30 days.
Calculate this yourself?

Frequently asked questions
Can I always switch between fresh and dried?
Not always. Some dishes specifically call for fresh (like caprese salad with fresh basil) or dried (like pizza herbs). Always test the flavor result before you switch permanently.
How often should I update prices?
For fresh ingredients: monthly, especially during seasonal changes. For dried ingredients: quarterly, unless your supplier notifies you of price changes. Fresh ingredients fluctuate much more.
Should I include waste in the calculation?
Yes, for fresh ingredients. Calculate with the usable weight after processing. Fresh herbs often have 10-20% waste (thick stems). For dried ingredients you calculate with 100% usable.
What if the flavor changes?
Adjust your recipe by tweaking the quantity, but keep the conversion factor for your cost price calculation. Some dishes taste different with fresh versus dried - that's normal.
