Not sure how to test the oil temperature? Fear not, here are a few handy little tips for hoe to check hot hot the oil is if you don't have a thermometer.
1) The handle of a wooden spoon / wooden chopstick
When the oil has preheated, dip the handle of a wooden spoon or a chopstick into the oil. If the oil starts steadily bubbling, then the oil is hot enough for frying. If the oil bubbles very very vigorously, then the oil is too hot and needs to cool off a touch. If no or very few bubbles pop up, then it’s not hot enough.
2) A piece of bread
Drop a 1-inch square of bread into the oil. If it takes 60 seconds to brown, then the oil is at 365°F.
3) Popcorn kernels
Drop a single kernel of popcorn into the oil as it is heating. The kernel will pop as the oil reaches between 350°F and 360°F. (Remove the kernel, eat it, and start frying!)
Once the oil has reached the right temperature, the most important to remember is not to overcrowd the pan - samosa-distancing is a must! Fry the samosas is small batches, so the little parcels have space to move around and they will cook to perfections.
