When using strobe lighting, if you are not careful, the food might look not delicious.
A good food lighting makes the food to look delicious, showing right mood of the setting.
It shows well the moisture on food, colors, and textures of food. The textures and colors of food( raw or cooked) can be very amazing.
Showing moisture on food well is important. Otherwise, the food would look dry and old. This happens when the light source is too small and placed at a wrong angle.
Window light can be very good light if...you can control the sun, clouds, time..
when using strobe light, it becomes more difficult. Obviously, you are controlling a kind of sun, clouds, time..
Think over the relative size of light source(diffusion size, the position in relations of strobe, diffusion, subject) for the food(sometimes bigger is good as long as you maintain the directional quality of light and interesting tone variation in an image.. not always of course..), directional quality of the light(you need some directional quality to show the textures well. Avoid too thick diffusion material..). ALso test for the right angles in relationship for camera, subject, and the lighting.
At a some angle, you can feel that it is the best for the specific food subject. For some cases, you need some flare effect? on food( a certain back lit angle to make the food reflect light...delicious..). Sorry for the vague answers. But unless you go deeper with lighting and testing various angles, light quality, you can't make it interesting. Think about this situation when in a very early morning on the street, when you are walking, and the sun is rising in front of you at a certain angle, you can see the asphalt surface of street is flaring, melting with light in a mysterious and beautiful way...Also did you see the light green leaves of a tree, are melting with sun light?... where the leaves becomes light. There are no boundaries between them.. This is one of most beautiful visual sighting you can experience. You need to understand this light quality(light-size, directional-softness quality, angles..) and need to create this with strobe light to lit the food well.
