The difference between penne and rigatoni
Penne and rigatoni seem very similar, they're both tube shaped pastas. There are a few points that make them different to one another:
Penne vs. rigatoni
1. Penne is cut on the bias, or diagonal, giving it a pointed shape. Rigatoni is cut straight, giving it a cylindrical shape.
2. Rigatoni always has ridges around the outside. Penne may be smooth or have ridges.
3. Rigatoni have a slightly larger circumference than penne.
4. Penne are always straight, whereas rigatoni may have a slight curve.
Can you substitute penne and rigatoni?
Yes, in a pinch you can substitute penne or rigatoni in any pasta dish that calls for either. The only thing to note is that if you use smooth penne it will have a different mouthfeel, and won't hold as much sauce as ridged penne or rigatoni.
What about ziti?
Ziti is straight cut like rigatoni, but is smooth on the outside. It's more popular in America than Australia, and is often used in "Baked Ziti" pasta bakes. Much like rigatoni and penne, it's easily interchangeable with these other pasta shapes.
