Consider:

I have tried playing with the displace modifier and various texture, but I cannot seem to find the right combination.

    Hello :). Displacement seems like a good approach. What's your current result? And have you tried nodes displacement? – jachym michal Apr 18 '21 at 11:12

It looks like a noisy volume to mesh transformation might work for you. Perhaps a modified "Swiss Cheese" geo_node setup (below) would work with a noisy displacement shader added. Best of luck :) Sorry, Author unknown.

On second thought... Here is a material nodes only answer: Nodes: It will take a pretty dense mesh: Vert count: But, It renders pretty quickly. Render:

You could:

  • Subdivide a cube, sculpt it:

  • Give it a Displace modifier with a Cloud as Texture:

  • Add some fake displacement with 2 levels of bump noises:

  • Select random faces, extrude along normals in order to dig some holes:

  • Deform the whole shape with the Proportional Editing on:

  • Work on the color to give it small grains, create a vertex paint mask in order to create an area with a different color:

  • Etc...
